What is a force?

• A. A push or pull

• B. A change in position

• C. Measurement of motion

• D. Gravity

What causes motion?

• A. Balanced forces

• B. Unbalanced forces

• C. Gravity

• D. Velocity

What is motion?

• A. A push or pull

• B. Change in position

• C. Measurement of motion

• D. Gravity force

What is velocity?

• A push or pull on an object

• A change in an object's position

• The measurement of an object's motion

• The force of gravity

What is acceleration?

• A push or pull on an object

• A change in an object's position

• The measurement of an object's motion

• The change in an object's velocity

What is Newton's first law of motion?

• A. An object at rest stays at rest and an object in motion stays in motion unless acted upon by an outside force

• B. The force on an object equals its mass times acceleration

• C. Every action has an equal and opposite reaction

• D. More mass requires more force to move an object

What is Newton's second law of motion?

• A. An object at rest stays at rest and an object in motion stays in motion unless acted upon by an outside force

• B. The force on an object equals its mass times its acceleration

• C. Every action has an equal and opposite reaction

• D. More mass requires more force to move an object

What is Newton's third law of motion?

• A. An object at rest stays at rest and an object in motion stays in motion unless acted upon by an outside force

• B. The force on an object equals its mass times its acceleration

• C. Every action has an equal and opposite reaction

• D. More mass requires more force to move an object

What determines if an object is moving or still?

• A. Balanced forces

• B. Unbalanced forces

• C. Gravity

• D. Velocity

What happens when forces are unbalanced?

• A. The object remains still

• B. The object moves in the opposite direction

• C. The object moves in the same direction

• D. The object accelerates
