Motion and Forces

Front

What is Newton's 1st Law of Motion?

Back

An object in motion (or at rest) will stay in motion (or at rest) until an outside force acts upon it.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied. (F=ma)

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is unbalanced force?

Back

Forces that are not equal and can cause an object to change its motion.

Front

What is potential energy?

Back

Energy stored in an object due to its position or state, such as a rock at the edge of a cliff.

Front

What is kinetic energy?

Back

Energy of an object in motion.

Front

What is friction?

Back

A force that opposes the motion of an object, acting between surfaces in contact.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What is inertia?

Back

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