Force & Motion Quiz

Force is

• a push or pull on an object causing it to move, change direction or shape.

• an unbalanced force allowing it to have inertia.

• an acceleration of speed creating a balanced force.

• a pull of gravity on the body.

Two classes are playing tug-of-war. If the center of the rope is not moving, what must be true? (Choose all that apply)

• Both classes are pulling equally.

• Both classes have equal mass.

• The forces are balanced.

• One class is pulling harder than the other.

When objects remain in the same place, it is called...

• gravity

• friction

• balanced force

• unbalanced force

What is the force that causes everything to be pulled down to the Earth?

• unbalanced

• balanced

• friction

• gravity

Force is measured in....Galile

• Galileos 

• Newtons

• Di Vincis

• Einsteins 

An unbalanced force is

• is when an object stays at rest. because of a push.

• when objects move in one direction because the force is greater from that direction.

• keeps an object sitting still

• a pull on the earth.

Newton's First Law of Motion states Inertia is....

• larger objects take more force to move 

• for every action, there is an equal and opposite reaction

• a push that acts in the opposite direction and it slows down.

• an object in motion tends to stay in motion unless acted on by an opposite force

 

Friction helps objects to

• slow down.

• move faster.

• to continue to have motion.

• a force that pulls one to the Earth.
