Newtons laws

Front

What is Newton's 1st 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 a net external force.

Front

What is Newton's 2nd 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 the formula F = ma.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

Define mass in the context of physics.

Back

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

Front

What is inertia?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its motion.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = ma, where m is mass and a is acceleration.

Front

What happens to a moving object when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

Give an example of Newton's 1st Law in everyday life.

Back

A book resting on a table will remain at rest until someone pushes it.

Front

Explain the relationship between force, mass, and acceleration.

Back

If the mass of an object increases while the force remains constant, the acceleration decreases.
