Physics Pre-Assessment

A push or pull placed on an object is called

• force

• motion

• acceleration

• velocity

It is part of physics that studies the laws and motion of an object

• Kinematics

• Classical Mechanics

• Newton's law

• Quantum Mechanics

The total sum of forces acting on an object.

• net force
• potential energy
• rest
• trial

If you have balanced forces on a soccer ball, what will happen?

• Nothing, it will not move

• It changes its motion to speed up

• It changes its motion to slow down

• It changes its motion to turn

Energy that an object has due to its motion.

• potential energy
• kinetic energy
• energy
• force

Which of the following is an example of acceleration?

• A car which had been moving comes to a complete stop.

• A car which had been moving at 30 mph is now moving at 55 mph.

• A car which had been moving north turns to the east while still traveling at 30 mph.

• All of the above.

When there is a change in an object's motion, what is caused?

• balanced force

• net force

• unbalanced force

Friction is a force that acts in the _____________________ direction of a moving object to slow it down.

• same

• fastest

• equal

• opposite
