Forces and 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 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

What is gravity?

Back

Gravity is the force of attraction between two objects that have mass.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface.

Front

What is mass?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate at which an object's velocity changes over time.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).
