Impulse Physics

An impulse depends on

• weight and force

• force and time

• electric charge and time

• none of these

If the change of momentum of an object is 50kg m/s, we can say the impulse is equal to:

• 0 kg m/s

• 25 kg m/s

• 50 kg m/s

• 100 kg m/s

Definition of impulse:

• The time integral of net force that causes Change in momentum

• The product of mass and velocity

• The ability to do work

• the rate of increase of speed or the rate of change of velocity

If you push an object with a force of 10 N for 5 seconds , you will change it’s momentum by:

• 2 N s

• 50 N s

• 2 N/s

• 50 N/s

The graph shows the force on an object of mass M as a function of time. For the time interval 0 to 4 s, the total change in the momentum of the object is

• 40 kg m/s 

• 20 kg m/s

• 0 kg m/s 

• – 20 kg m/s

Check ALL that apply.

Impulse is:

• The force that creates an acceleration.

• The change in momentum.

• the change in velocity that can be caused by a constant force over some discrete amount of time.

• A vector

• NOT a vector
