Forces

Front

What are forces?

Back

Forces are pushes and pulls that can change the motion of an object.

Front

How do we measure forces?

Back

Forces are measured using a Newton Meter.

Front

What is drag?

Back

Drag is a force that opposes the motion of an object through a fluid, like air or water.

Front

What is engine force?

Back

Engine force is the force produced by an engine to move a vehicle forward.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity.

Front

What is the reaction force?

Back

The reaction force is the force exerted by a surface in response to an object pressing against it.

Front

What does it mean for forces to come in pairs?

Back

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

Front

What is the role of friction in forces?

Back

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

Front

What is a balanced force?

Back

Balanced forces occur when two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Unbalanced forces occur when one force is greater than the other, causing a change in the object's motion.
