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 inertia.

Back

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

Front

What is the formula to calculate force?

Back

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

Front

If a 5 kg object is accelerated at 2 m/s², what is the force applied?

Back

10 N (Force = 5 kg × 2 m/s²).

Front

What happens to the acceleration of an object if the mass is doubled while the force remains constant?

Back

The acceleration is halved.

Front

Give an example of Newton's First Law of Motion in everyday life.

Back

A soccer ball remains stationary until a player kicks it.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

How does friction affect motion according to Newton's laws?

Back

Friction opposes motion and can affect the net force acting on an object.
