Newton's 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 at a constant velocity unless acted upon by a net external 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

Define net force.

Back

The vector sum of all the forces acting on an object.

Front

What is the relationship between mass and acceleration according to Newton's Second Law?

Back

Acceleration is inversely proportional to mass; as mass increases, acceleration decreases for a given net force.

Front

What happens to an object in motion if no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What is inertia?

Back

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

Front

How does friction affect motion?

Back

Friction opposes the motion of an object, requiring a greater net force to achieve acceleration.

Front

What is the formula for calculating force?

Back

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

Front

What is the effect of a greater net force on an object's acceleration?

Back

A greater net force results in a greater acceleration, assuming mass remains constant.
