Submit quiz
Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
Newton's second law in its momentum form states that resultant force equals
mass × velocity
impulse × time
change in kinetic energy
rate of change of momentum
2.
The area under a force-time graph represents
work done
change in momentum
power
acceleration
3.
A 0.50 kg ball moving at 6.0 m s-1 is stopped in 0.10 s. The average force is
30 N
3.0 N
0.30 N
300 N
4.
A seat belt reduces injury because it
reduces the change in momentum
makes the car stop faster
increases the passenger's mass
increases the stopping time and so reduces the force
5.
A force of 8.0 N acts for 3.0 s on a 4.0 kg object initially at rest. The final velocity is
2.0 m s-1
6.0 m s-1
24 m s-1
0.67 m s-1
6.
A jet of water that rebounds elastically from a wall exerts, compared with one that stops dead,
half the force
the same force
twice the force
no force
