Momentum and Acceleration

Front

If an object is accelerating, there is a force present.

Back

True

Front

A shark is swimming at a speed of 14m/s until it senses a fish and speeds up at a rate of 20m/s and catches it in 3 seconds. What was the shark's acceleration?

Back

2m/s²

Front

Acceleration

Back

A change in velocity over time.

Front

If velocity changes, momentum changes, therefore a force is present.

Back

True

Front

A stunt car crashes into a wall with a momentum of 46,500Ns. The mass of the car is 1,500 kg. How fast was the car going?

Back

31 m/s

Front

If a car is going at a constant velocity, does the car have a change in momentum?

Back

No

Front

A 2kg ball is rolling down the street at a speed of 5 m/s. It eventually rolls down a hill and speeds up to 10 m/s. What was the ball's change in momentum?

Back

10 kg*m/s

Front

Is it possible for acceleration and momentum to happen at the same time?

Back

Yes
