A force is a push or a pull on an object that results from its interaction with another object.

• True
• False

Only large objects with mass have gravity.

• True
• False

The combined force of all forces acting on an object is the  ___ force.

• net
• big
• bad
• use

When the forces acting upon an object are UNBALANCED , the object will ____

• stay still
• move
• bounce
• fly

Acceleration is a change in _____

• velocity
• cars
• school
• me

Newton's second law is applied as the formula _____

• Force = Mass X Acceleration
• Speed = distance / time
• a + b = c
• huh?

Which of the following explains the difference between speed and velocity?

• One has motion, and the other does not.
• One has direction, and the other does not.
• One involves time, and the other does not.
• One involves acceleration, and the other does not.

Acceleration is caused by a force acting on a mass.

• Newton’s first law of motion
• Newton’s second law of motion
• Newton’s third law of motion

For a force on an object there is an equal and opposite force.

• Newton’s first law of motion
• Newton’s second law of motion
• Newton’s third law of motion

In order to be ____ forces, their effects must cancel each other out and not cause a change in an object's motion.

• balanced
• strong
• weak
• normal
