Momentum, Impulse, and Collisions

Front

For every action, there is an equal and opposite reaction is also known as____.

Back

Newton's 3rd Law of Motion

Front

An insect applies 1.5 N of force to a windshield of a moving car. How much force does the windshield apply to the insect?

Back

1.5 N

Front

A runner has a momentum of 670 kg m/s and is traveling at a velocity of 9 m/s. What is his mass?

Back

74.4 kg

Front

Which cart applies a GREATER FORCE during the collision (according to Newton's 3rd Law)?

Back

Forces are EQUAL for BOTH carts

Front

What kind of collision is this?

Back

inelastic collision

Front

Define momentum.

Back

Momentum is the product of an object's mass and its velocity, represented as p = mv.

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time, calculated as Impulse = Force × Time.

Front

What is the formula for calculating momentum?

Back

p = mv, where p is momentum, m is mass, and v is velocity.

Front

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, kinetic energy is conserved; in inelastic collisions, kinetic energy is not conserved.

Front

State Newton's 1st Law of Motion.

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.
