a roller coaster sitting motionless while passengers get on
a roller coaster going around a loop at a constant speed
Which of the following describes the motion of the door?
increasing speed to the left

If this cylinder has a mass of 20 kilograms, what is its rate of acceleration? (hint: ___ N = 20 kg x a)
0 m/s2
65 m/s2
1 m/s2
20 m/s2
The white car hit the gray car, yet both cars were damaged. Why is that?
An object at rest will remain at rest unless acted on by an unbalanced force.
If you apply more force to an object, it will accelerate more.
For every action, there is an equal and opposite reaction.
Given the FBD, which of the following must be true?
The frictional force must be accelerating the system to the left.
The box must be accelerating to the right.
The box must be moving to the right.
The FBD is incorrectly drawn. This situation isn't possible
Which of the following statements is true about the image above?
The accelerations of the blocks will vary according to their mass
The net force acting on each block is the same
The blocks will experience the same acceleration
The 3m box will eat the 2m and the m boxes
A 100 kg skydiver is free falling at a constant velocity of 20 m/s. What is the net (total) force acting on them?
2,000 N
0 N
980 N
