Forces and motion

Front

What is force?

Back

A push or pull on an object.

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What does Newton's First Law of Motion state?

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 Newton's Second Law of Motion describe?

Back

The relationship between force, mass, and acceleration, expressed as F=ma.

Front

What is Newton's Third Law of Motion?

Back

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

Front

How can you increase the speed of a toy car on a ramp?

Back

By applying more force to it.

Front

What happens to the motion of an object when friction is reduced?

Back

The object moves more easily and can accelerate faster.

Front

What is the role of a slippery pad when moving heavy objects?

Back

It reduces friction, making it easier to move the object.

Front

What is the effect of increasing the force applied to an object?

Back

It increases the object's acceleration.
