The force exerted perpendicular to the surface an object rests on is known as:
the normal force.
friction.
gravity.
the electromagnetic force.
The gravitational force that an object exerts due to its mass is called:
weight.
mass.
friction.
acceleration.
The resistance of an object to a change in motion is referred to as:
inertia.
mass.
acceleration.
velocity.

off
low
medium
high
In the Force and Fan Carts Gizmo, what was the result of the cart moving over surfaces with more friction.
the speed was lower
the speed was higher
the speed was the same
the cart didn't move at all
In the Force and Fan Carts Gizmo, what was the result of adding mass to the cart?

A cart is set up as shown below, with three fans directed to the left and two of the fans running. The motion of the cart is represented by the v vs t graph shown. If the experiment were repeated with all three fans running, what might the resulting v vs t graph look like?
According to the graph of v vs. t, what was the initial velocity of the cart?
0.0 m/s
0.5 m/s
1.0 m/s
1.5 m/s
A cart with one fan on it blowing to the left and carrying one block produces the x vs. t graph shown. If the cart were carrying three blocks instead of one, with the fan still blowing in the same direction, what could the x vs. t graph look like
Newton's first law of motion states that:
objects tend to keep on doing what they're doing.
for every action there is an equal and opposite reaction.
forces occur in pairs.
acceleration equals force divided by mass.
A force is not needed to keep an object in motion.
True
False
Unknown
Suppose that there are two seemingly identical bricks at rest on a physics lab table. One brick consists of mortar and the other brick consists of Styrofoam. Without lifting the bricks, how could you tell which brick was the Styrofoam brick?
Give both bricks an identical push in an effort to change their state of motion. The brick that offers the least resistance is the brick with the least inertia, Styrofoam.
Put the bricks on a triple-beam balance and measure their masses. The brick with the least mass will be the Styrofoam brick.
Throw both bricks at pane of glass. The one that DOES NOT break the glass is Styrofoam.
If one is heavy enough to fall through the table, then the other one is Styrofoam.
Newton's 2nd Law states that F = ma.
In the free body diagram above, what would happen if the forces were unchanged but the object were more massive?
The object would accelerate at a slower rate.
The object would accelerate at a faster rate.
The object would lose mass.
The object would become even more massive.
A single force can never exist all by itself.
True
False
A large wooden crate is being pushed across the floor. Which of the following is an interaction pair for the system described?
