Forces and Force Diagrams

Front

What is the force that keeps objects on top of surfaces instead of letting them sink into the surface?

Back

Normal Force

Front

What is the sum of all forces acting on an object and their direction called?

Back

Net Force

Front

What does Newton's First Law state about an object in motion and an object at rest?

Back

An object in motion will stay in motion and an object at rest will stay at rest unless acted on by an outside force.

Front

What is the force that opposes the motion of an object sliding on a surface?

Back

Friction Force

Front

What is the force exerted by the Earth on an object due to its mass?

Back

Gravitational Force

Front

What is the term for forces that are equal in size but opposite in direction?

Back

Balanced Forces

Front

What is the term for forces that are not equal and cause a change in motion?

Back

Unbalanced Forces

Front

What is the force that acts against the motion of an object moving through air?

Back

Air Resistance

Front

What is a force diagram?

Back

A visual representation of all the forces acting on an object.

Front

What happens to an object when the net force acting on it is zero?

Back

The object remains at rest or continues to move at a constant velocity.
