Newtons 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 unless acted upon by a net external force.

Front

What does it mean for forces to be balanced?

Back

Forces are balanced when the net force acting on an object is zero, resulting in no acceleration.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surface of contact.

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 happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.

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, making it harder to change its motion.

Front

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

Back

A passenger lurches forward in a car when it suddenly stops.

Front

What is the role of friction in motion?

Back

Friction can slow down or stop the motion of an object, and it is necessary for walking or driving.
