Momentum and Impulse

Front

An object that has momentum can be described as _________

Back

d) having its mass in motion

Front

What is the formula for calculating momentum?

Back

Momentum (p) = mass (m) × velocity (v)

Front

A 0.250 kg cart moving at 0.400 m/s has how much momentum?

Back

0.1 kg-m/s

Front

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

Back

Total Momentum

Front

Padded dashboards in cars are safer in accidents than non padded ones because the passenger hitting the dash has...

Back

e) a and c (Increased time of impact and decreased impact force)

Front

Which takes more force to catch, a bowling ball or a ping pong ball?

Back

Bowling ball because it has more momentum

Front

Define impulse in terms of momentum.

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 force?

Back

Impulse = Force × Time

Front

If a car's momentum changes from 200 kg-m/s to 100 kg-m/s, what is the impulse experienced by the car?

Back

Impulse = Change in momentum = 100 kg-m/s

Front

What happens to momentum in a closed system during a collision?

Back

Momentum is conserved.
