Which statement best summarizes the scientific concept shown in the cartoon?
A falling body accelerates at a constant speed.
The motion of an object is constantly changing due to magnetic forces.
The force of friction causes an object in motion to move faster.
A body in motion will remain in motion unless influenced by an outside force.
An object accelerates at 3 m/s2 when a 10 N force is applied to it. Which force would cause this object to accelerate at 6 m/s2?
5 N
10 N
20 N
30 N
Water comes through a hose and is sprayed by the sprinkler. Which principle best explains why the sprinkler spins?
Every action has an equal and opposite reaction.
Solid substances are usually more dense than liquid substances.

What causes the balloon to move along the string?
force from string
friction between string and straw
force from escaping air
weight of balloon containing air
In a car accident, a seat belt helps prevent injuries by applying a force
less than the force of the moving passenger
greater than the force of the moving car
in the same direction as the car’s motion
in the opposite direction of the passenger’s motion
The arrows in this diagram represent the forces acting on a moving bicycle at two different times, time 1 and time 2. The length of each arrow represents the amount of force being applied.
As a result of the change in the forces from time 1 to time 2, the bicyclist will
move slower in a forward direction
move in a backward direction
move faster in a forward direction
stop moving
