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 at a constant velocity unless acted upon by a net external force.

Front

What is inertia?

Back

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

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 the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What are the units of force?

Back

Newtons (N).

Front

What are the units of mass?

Back

Kilograms (kg).

Front

What are the units of acceleration?

Back

Meters per second squared (m/s²).

Front

What happens to an object when the forces acting on it are balanced?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What happens to an object when the forces acting on it are unbalanced?

Back

The object will accelerate in the direction of the net force.
