Front

What is the relationship between force and motion?

Back

Force causes changes in motion; an unbalanced force results in acceleration.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is mass?

Back

The amount of matter in an object, which affects its inertia.

Front

What is weight?

Back

The force of gravity acting on an object, calculated as mass times the acceleration due to gravity (W=mg).
