Newtons Laws

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 with the same speed and in the same direction unless acted upon by an unbalanced 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 Newton's Third Law of Motion?

Back

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

Front

What is a force?

Back

A push or pull on an object that can cause it to change its velocity.

Front

What is an unbalanced force?

Back

A force that causes a change in the motion of an object because the forces acting on it are not equal.

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, commonly experienced as the force that pulls objects toward the Earth.

Front

What is friction?

Back

A force that opposes the motion of an object when it is in contact with another surface.

Front

What is mass?

Back

The amount of matter in an object, typically measured in kilograms.

Front

What is weight?

Back

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