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 unless acted upon by a net external force.

Front

What is inertia?

Back

Inertia is 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 is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass × gravity.

Front

What is air resistance?

Back

Air resistance is a type of friction that acts against the motion of an object moving through air.

Front

What is the role of gravity in motion?

Back

Gravity is a force that attracts objects toward each other, affecting their motion and weight.

Front

What is an example of action and reaction?

Back

When a swimmer pushes water backward (action), they move forward (reaction).
