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 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. This is often expressed as F = ma.

Front

What is Newton's Third Law of Motion?

Back

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

Front

How does mass affect acceleration when a constant force is applied?

Back

As mass increases, acceleration decreases when the same force is applied, according to Newton's Second Law.

Front

What is the formula to calculate force?

Back

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

Front

If a 10 kg object is accelerated at 2 m/s², what is the force applied?

Back

Force = 10 kg × 2 m/s² = 20 N.

Front

What happens to the acceleration of an object if the net force acting on it is doubled?

Back

The acceleration will also double, assuming the mass remains constant.

Front

What is inertia?

Back

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

Front

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

Back

Friction is a force that opposes motion, affecting the net force and thus the acceleration of an object.

Front

What is the relationship between force, mass, and acceleration?

Back

The relationship is defined by Newton's Second Law: F = ma.
