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 the formula 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 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 kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, such as gravitational potential energy.

Front

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

Back

According to Newton's Second Law, force equals mass times acceleration (F=ma).

Front

What happens to the acceleration if the force applied is decreased?

Back

The acceleration will decrease if the force applied is decreased, assuming mass remains constant.

Front

What is an example of Newton's First Law in everyday life?

Back

A passenger in a car continues to move forward when the car suddenly stops, demonstrating inertia.
