Forces and Net Force

Front

What is an applied force?

Back

An applied force is a force that is applied to an object by a person or another object.

Front

What is a balanced force?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in a net force of zero Newtons.

Front

What is an unbalanced force?

Back

Unbalanced forces are forces that are not equal in size or direction, resulting in a net force that causes an object to accelerate.

Front

What happens when forces are balanced?

Back

When forces are balanced, the object remains at rest or continues to move at a constant speed.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will accelerate in the direction of the net force.

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is gravity?

Back

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

Front

What is normal force?

Back

Normal force is the support force exerted upon an object that is in contact with another stable object, acting perpendicular to the surface.

Front

What is air resistance?

Back

Air resistance is a type of frictional force that opposes the motion of an object through the air.

Front

What is the net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined.
