9 kg

Front

A bicycle has a momentum of 36 kg • m/s and a velocity of 4 m/s. What is the mass of the bicycle?

Back

Remains the same

Front

The law of conservation of momentum states that, if left alone, the total momentum of two interacting objects that make up a system .

Back

The ball pushing the person

Front

When someone throws a ball, the action force is the person pushing on the ball. What is the reaction force?

Back

It extends the time of the collision

Front

Football helmets are made with padding that helps reduce head injuries when a player collides with an object. Which best explains how the padding reduces injuries?

Back

6.0 kg m/s

Front

What is the momentum of a 5 kg object that has a velocity of 1.2 m/s?

Back

Inelastic Collision

Front

Two objects sticking to each other.

Back

Persistence of motion

Front

momentum

Back

0.2 kg m/s

Front

The diagram shows two balls before they collide. What is the momentum of the system after the collision?

Back

The pin pushes the bowling ball toward the left

Front

A bowling ball collides with a pin and pushes the pin toward the right. Which describes the reaction force

Back

M

Front

Mass measured in kilograms (kg)

Back

Friction

Front

Force that opposes motion between two surfaces.

Back

p initial = p final

Front

Which formula can be used to express the law of conservation of momentum, where p = momentum?

Back

Gravity

Front

Force that pulls all objects together "closer the objects, the harder the pull" "greater the mass, larger the pull"; acceleration due to gravity is 9.8 m/s/s on earth (if it weren't for air resistance).

Back

Mass

Front

The amount of matter in an object; SI unit for measuring mass is the kilogram.

Back

Momentum Formula

Front

P = M(V)

Back

The grass extends the time of the collision

Front

Denise is riding her bike and falls to the ground. During the collision, she hits both grass and cement.

Back

Elastic collision

Front

Two objects bounce off each other.

Back

Weight

Front

A measure of the force of gravity pulling down on your body; unit for measuring weight is the Newton.

Back

Law of Conservation of Momentum

Front

Momentum is not lost in a collision

Back

action force and reaction force

Front

According to Newton's third law of motion, which are equal?

Back

Z

Front

The chart lists the masses and velocities of four objects. Which object requires the greatest change in momentum in order to stop its motion?

Back

4 kg m/s

Front

Two carts collide and bounce apart. Cart 1 had a momentum of -6 kg • m/s before the collision. Cart 2 had a momentum of 10 kg • m/s before the collision. What is the total momentum of the carts after the collision?

Back

1,500 kg- m/s

Front

The chart show the masses and velocities of two colliding objects that stick together after a collision. According to the law of conservation of momentum, the momentum of the object after the collision is ____ kg • m/s.

Back

Collision

Front

A situation in which two objects in close contact exchange energy and momentum.

Back

P

Front

Momentum measured in Newton Seconds (Ns)

Back

It is equal to the momentum of object 1 plus the momentum of object 2.

Front

Objects 1 and 2 collide and stick together. Which best describes the momentum of the resulting single object?

Back

Impulse

Front

Change in momentum

Back

Velocity

Front

The speed of the object and the direction of its motion.

Back

Inertia

Front

A body at motion stays in motion unless acted on by an outside force and a body at rest stays at rest.

Back

Y, W, X, Z

Front

The chart shows masses and velocities of four objects. Which lists the objects in order, from least to greatest momentum?

Back

The red ball has a greater velocity than the purple ball

Front

The chart lists the masses of four balls that have the same momentum. Which correctly compares two of the balls?

Back

V

Front

Velocity measured in meters per second (m/s)

Back

40,000 kg m/s

Front

A car has a momentum of 20,000 kg • m/s. What would the car's momentum be if its velocity doubles?

Back
