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 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

What does the 'F' represent in the equation F = ma?

Back

'F' represents the net force acting on an object.

Front

What does the 'm' represent in the equation F = ma?

Back

'm' represents the mass of the object.

Front

What does the 'a' represent in the equation F = ma?

Back

'a' represents the acceleration of the object.

Front

What is the relationship between force and acceleration?

Back

The greater the force applied to an object, the greater the acceleration produced.

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 an example of Newton's Third Law of Motion?

Back

When you jump off a small boat, you push the boat backward as you move forward.
