Newton's 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 the formula for calculating force?

Back

Force (F) = Mass (m) × Acceleration (a)

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

What is the Law of Action-Reaction?

Back

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

Front

What is gravity?

Back

The attractive force that exists between all objects that have mass.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N)

Front

How do you calculate weight?

Back

Weight (W) = Mass (m) × Gravitational acceleration (g), where g is approximately 9.81 m/s² on Earth.

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 an unbalanced force?

Back

A force that results in a change in the motion of an object, causing it to accelerate.

Front

What is inertia?

Back

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