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 an unbalanced force?

Back

A force that causes an object to change its state of motion (acceleration) because it is not equal and opposite to other forces acting on the object.

Front

What is acceleration?

Back

The rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is the formula for calculating force?

Back

F = m x a, where F is force, m is mass, and a is acceleration.

Front

What unit is force measured in?

Back

Newtons (N).

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.

Front

If a 10 kg object is accelerating at 5 m/s², what is the force acting on it?

Back

F = m x a = 10 kg x 5 m/s² = 50 Newtons.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is gravity?

Back

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