If an object is accelerating, there is a force present.
True
False
Which of these graphs show a constant velocity?
Which of these graphs show acceleration?
A shark is swimming at a speed of 14m/s until it senses a fish and speeds up up at a rate of 20m/s and catches it in 3 seconds. What was the shark's acceleration?
10 m/s2
0.5 m/s2
2m/s2
5 m/s2
Which one of these is the definition for acceleration?
A change in velocity over time.
A certain distance covered during a second.
The product of mass and velocity.
The amount of energy required to stop an object.
If velocity changes, momentum changes, therefore a force is present.
True
False
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?
54 m/s
120 m/s
15 m/s
31 m/s
If a car is going at a constant velocity, does the car have a change in momentum?
Yes
No
Maybe
Not enough information

None of the above
A Jedi
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?
30 kg*m/s
10 kg*m/s
25 kg*m/s
100 kg*m/s
Challenge question: Is it possible for acceleration and momentum to happen at the same time?
Yes
No
