2.
A student places a toy car on a track with a rough surface.
In which situation is a net force of zero acting on the toy car?
a)
The car is pushed around a curved section of track so that it maintains the same speed.
b)
The car is pushed along a straight section of track so it maintains the same speed.
c)
The car is given a quick push along any section of track and then allowed to come to a stop.
d)
The car is pulled along any section of track so that its speed increases by the same amount each second.
3.
When four forces are applied to a box, the box begins to move. The diagram's arrows show the direction and the
magnitude of the four forces acting on the box.
In which direction will the box move?
a)
In the direction arrow P is pointing
b)
In the direction arrow Q is pointing
c)
In the direction arrow R is pointing
d)
In the direction arrow S is pointing
4.
An object moves at a constant speed.
What will happen to this object's motion over time if no new forces are applied?
a)
It will change direction.
b)
It will increase in speed
c)
It will decrease in speed.
d)
It will maintain a constant speed.
5.
A battery-powered toy submarine is moving through water at constant speed and at a constant depth below the surface. The diagram shows the submarine with arrows representing the directions but not the magnitudes of four forces acting on it.
Which conclusion can be made about the magnitudes of the forces acting on the submarine?
a)
Force Q is equal to Force S and Force R is equal to Force T
b)
Force Q is less than Force S and Force R is equal to Force T.
c)
Force Q is equal to Force S and Force R is greater than Force T
d)
Force Q is less than Force S and Force R is greater than Force T.
6.

a)
Box X starts moving, speeding up, and Box Y remains at rest.
b)
Box X starts moving at constant speed, Box y remains at rest.
c)
Box X starts moving at constant speed, and Box Y starts moving, speeding up.
d)
Box X starts moving, speeding up, and Box Y starts moving at a constant speed.
9.

a)
a toy car rolling faster down a ramp
b)
a car remaining parked in a parking lot
c)
a bike moving at a constant speed around a circular track
d)
a truck slowly speeding up after being stopped at a stoplight
