Momentum and Impulse

Front

The momentum of an object depends upon the object's ___________&_____________.

Back

mass and velocity.

Front

A 10kg toy truck moves at 5m/s East. It collides head-on with a 5kg toy car moving 10 m/s moving west. What is the total momentum of the system?

Back

0 kgm/s.

Front

Softer landings tend to __________.

Back

increase collision time.

Front

An object that has momentum can be described as _________.

Back

having its mass in motion.

Front

In any collision (crash) the ______ is ALWAYS constant.

Back

Total Momentum.

Front

Define momentum.

Back

Momentum is the product of an object's mass and its velocity.

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 impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time.

Front

What is the relationship between impulse and momentum?

Back

Impulse equals the change in momentum (Impulse = Δp).

Front

How does increasing the time of collision affect the force experienced?

Back

Increasing the time of collision decreases the force experienced.
