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 with the same speed and in the same direction 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 the formula to calculate force?

Back

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

Front

What is the definition of velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

If a 20 kg bike accelerates at 10 m/s², what is the force applied?

Back

200 Newtons.

Front

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

Back

The acceleration decreases.

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

As mass increases, acceleration decreases if the force is constant.

Front

What is inertia?

Back

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

How does a rocket launch using Newton's Third Law?

Back

A rocket pushes gases down, and in response, the rocket is propelled upward.
