Force and Motion

Front

What is the measure of the force of gravity on an object?

Back

Weight

Front

What are forces that produce a nonzero net force, which changes an object's motion?

Back

Unbalanced forces

Front

What is the force that opposes the motion of objects that move through the air?

Back

Air resistance

Front

What is the rate at which velocity changes?

Back

Acceleration

Front

What law states that an object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force?

Back

Newton's First Law

Front

What is the tendency of an object to resist changes in its state of motion?

Back

Inertia

Front

What is the force that attracts objects toward each other, commonly experienced as weight?

Back

Gravity

Front

What is the relationship between force, mass, and acceleration as described by Newton's Second Law?

Back

F = ma (Force equals mass times acceleration)

Front

What is the term for the quantity of motion an object has, dependent on its mass and velocity?

Back

Momentum

Front

What type of forces are equal in size and opposite in direction, resulting in no change in motion?

Back

Balanced forces
