Whenever an object is moving, there is always this force opposing the motion:
inertia
momentum
friction
applied force
The force that keeps objects on top of surfaces instead of letting them sink into the surface is known as:
normal
abnormal
static
inertia
The force exerted by ropes and chains is called
tension
normal
elastic
mechanical
In a force diagram, or free-body diagram, the size/length of the arrow tells you this about the force:
relative strength
relative distance
relative direction
In a force diagram, or free-body diagram, the pointy-end of the arrow tells you this about the force:
relative strength
relative distance
relative direction
When determining the NET force on an object you should (select TWO correct answers)
subtract forces in opposite directions
add forces in the same direction
divide by velocity
multiply by acceleration
What is the NET FORCE of this diagram?
17 N, right
17 N, left
23 N, right
12 N, up
This object would be moving (pick all that are correct):
up
down
left
right
The down-arrow in this diagram is most-likely:
gravity
normal
a push or pull
friction
Which diagram best shows person pushing a couch (accelerating) across the floor?
This diagram can be used to indicate which of the following? (TWO correct answers)
a object at rest
an object moving at a constant velocity (speed)
an object accelerating
(Trick question -- there is only one correct answer)
an object decelerating
Which of the following is true about this free-body diagram?
the forces are are balanced
the object is free-falling
the object is moving upward
the forces are unbalanced
Match description with free-body diagram.
A force is applied to the right to drag a sled across loosely packed snow with a rightward acceleration. Neglect air resistance.
A football is moving upwards towards its peak after having been booted by the punter. Neglect air resistance.
A car is coasting to the right and slowing down. Neglect air resistance.
A skydiver is descending with a constant velocity. Consider air resistance.
Describe the direction of the motion of this object.
The object is stopped because the forces are balanced.
The object is moving down because the down arrow is bigger.
The object is moving down because Drag is going up.
The object is moving up because the up arrow is bigger.
A golf ball accelerates off a tee, changing its velocity from 0m/s to 50 m/s down the fairway in 5 seconds. What is the golf ball's acceleration?
250 m/s2
45 m/s2
10 m/s2
0 m/s2
A ball of clay is thrown at a wall at a velocity of 28.0 m/s. The final velocity is 0.0 m/s. After it hits the wall, it takes 0.020 seconds to stop. What is the acceleration of the clay when it hits the wall?
1400 m/s2
-1400 m/s2
0.56 m/s2
-0.56 m/s2
The SI unit for acceleration is
mph
ft/sec2
m/s2
