You and your bike have a combined mass of 80 kg. Before opening Now, let's review quickly angular momentum. Brian, of a blob, what do you remember about As we go through equations of motion today, you will see the angle momentum expression, as seen by But we're already answering questions about that, right. People sometimes quickly assume to look at this So, provided that the mass of the object does not change, the motion of the object does not change its inertia.
- However, the velocity of the object affects its momentum, since momentum is the product of mass and velocity. Assuming positive motion when an object moving to the right. Since both objects moving along a straight line, the velocities have one component along the path of motion which a straight line and this component is either positive to the right or negative to the left.

TRUE - Momentum is a vector quantity. Like all vector quantities, the momentum of an object is not fully described until the direction of the momentum is identified. When that inertia is in motion, the object has momentum. TRUE - This is true. Possible answer: lifting an object up from the floor 2. Possible answer: Hitting a ball with a bat is a contact force. The noncontact force of gravity pulls a dropped object toward the floor. All objects are attracted to each other by a gravitational force.

- Chapter 6 Momentum and Collisions Angular momentum is the rotational counterpart of linear momentum. Any massive object that rotates about an axis carries angular momentum, including rotating flywheels, planets, stars, hurricanes, tornadoes, whirlpools, and so on. The helicopter shown in the chapter-opening picture can be used to illustrate the concept of angular momentum. Section Review 7. If the mass of the Sun is 1.

- Pressure causes pain. The person standing up exerts more pressure on the ground. Note that the person exerts the same force on the ground no matter what - her weight. When she is standing, her weight is applied to the ground through a small area the soles of her feet resulting in a relatively large pressure on the ground. When she lies down, the same force is applied over a much larger area her whole body resulting in less pressure on the ground. This is why you are told that "if you are on a frozen pond, and the ice starts to crack - lie down immediately! When you lie down, you exert the same force on the ice your weight , but over a much larger area.
- Therefore you exert less pressure on the ice. Pressure, not force, breaks the ice. The two rocks fall with the same acceleration because acceleration depends not only on the net force in this case, the net force on each rock is its weight , but also on mass. The net force on the 2 kg rock is its weight, 20 N mg. The net force on the 1 kg rock is its weight, 10 N. The heavier rock is being pulled toward the earth by twice as much force its weight , but it has twice as much inertia mass , so it resists accelerating twice as much. You have to pull twice as hard on the heavier rock to get it to accelerate at the same rate as the lighter rock! This question is much the same as question 12, but this answer is more abstract. Be sure that you understand question 12 first. The coin and the feather have the same acceleration of free fall because they have the same ratio of weight to mass.
- If an object is falling in air, there is an air resistance force, R, pushing on it upward in addition to its weight, mg, pulling it down. The air resistance force, R, on an object depends on its area and its speed relative to the air. Suppose that the coin and the feather have the same area. They don't have to, but you can work out the details for the other cases yourself. When they are traveling at the same speed, they would have the same air resistance force pushing on them, right? The bag of nails will reach its terminal speed when the net force on it is zero, which is when the upward air resistance force equals the downward weight force.
- Since the bag weighs N, it will reach terminal velocity when the air resistance force on it is N. An object will reach its terminal speed when the net force on it is zero, which is when the upward air resistance force equals the downward weight force. A skydiver will reach terminal velocity when the upward air resistance force on her equals the weight force pulling her down. Therefore, a heavy skydiver requires more air resistance force to reach terminal velocity than a light skydiver.

The air resistance force depends both on the surface area of the skydiver and on her speed relative to the air, so if two skydivers have the same area, the heavier one will have to be going faster in order to reach terminal velocity. In order to fall at the same rate, skydivers adjust their area. Heavy skydivers need more area to reach terminal velocity at a lower speed, so they could spread out their arms and legs and fall face down, for instance. Light skydivers need less area to reach terminal velocity at a higher speed, so they could pull in their arms and legs.- The net force on a 25 N freely falling no air resistance object is its weight, 25 N. If it encounters 15 N of air resistance, the net force on it is 10 N 25 N down, 15 N up. If it encounters 25 N of air resistance, the net force on it is zero - it will not accelerate, so it is at its terminal velocity. When A is -5, B is -5, too. To say that "A is proportional to B" means that A and B change in the same way. If an object has zero acceleration, you can conclude that the net force on it is zero.
- The net force on an object can be zero if a no forces push or pull on it, or b if all of the forces that push or pull on it cancel balance exactly. So, if the acceleration of an object is zero, you cannot conclude that no forces act on it. A free diagram that illustrates forces acting on an object that is not accelerating is in equilibrium could be something like:. As long as the forces balance exactly, you're OK. Its acceleration can't be zero, since if it were, its velocity would not change, right? If you throw a rock up into the air, it doesn't stay there, does it? Since the book is sliding at constant velocity, its acceleration is zero. Since its acceleration is zero, the net force on it must be zero Newton's First Law.
- Since the net force is zero, all of the forces on the book must cancel exactly. Therefore, the friction force on the book must be exactly 1 Newton. A sharp knife cuts better than a dull knife, because, for the same force, the sharp knife exerts more pressure than a dull knife. The sharp knife exerts its force over a small area of contact, which results in a large pressure. The dull knife exerts its force over a large area, which results in less pressure. Pressure cuts. Note: "Well, because it's sharp, stupid! As the skydiver falls faster and faster through the air, the net force on her decreases, and her acceleration decreases. As she falls, her weight mg pulls her down, and an air resistance force, R, pushes her up. As she falls faster and faster, the air resistance force on her increases, while her weight remains constant.
- Therefore, the net force on her decreases. She gains more speed during the first second of fall. Since acceleration is the rate velocity changes, velocity changes fastest when acceleration is greatest. She falls farthest during the ninth second of fall. Velocity is the rate position changes, so position changes fastest when the velocity is greatest. Since the skydiver has been accelerating for 9 seconds, she is moving the fastest during the ninth second. You are pushing the object twice as hard, but it is resisting twice as much!
- In other words, if you double the mass you get half the acceleration for the same force. Not assigned. The problem doesn't say that it's a real truck! If you would like kg, go ahead! Note: Yes, you really can make up your own numbers in this type of problem.
