Newtons Laws of Motion

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. This is often expressed as the formula F = ma.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What does 'balanced forces' mean?

Back

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

Front

What does 'unbalanced forces' mean?

Back

Forces that are not equal and opposite, resulting in a change in motion.

Front

How does mass affect the force required to move an object?

Back

The greater the mass of an object, the more force is required to accelerate it.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

F = ma (Force equals mass times acceleration).

Front

What happens to a marble rolling down a ramp in terms of forces?

Back

The forces acting on the marble are unbalanced, causing it to accelerate.

Front

What is an example of Newton's First Law in everyday life?

Back

A passenger lurches forward in a car when it suddenly stops.
