Forces Flashcard (6th Grade)

Front

What is work in physics?

Back

Work is done when a force acts on an object and the object moves in the direction of the force. It is measured in joules.

Front

What is a machine?

Back

A machine is a device that makes work easier by trading force for distance.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to move or change its motion.

Front

What is a balanced force?

Back

A balanced force is when two forces acting on an object are equal in size and opposite in direction, resulting in no motion.

Front

What unit is used to measure work?

Back

Work is measured in joules.

Front

What happens when two magnets with opposite poles are brought together?

Back

The north and south poles of two magnets attract each other.

Front

What is the relationship between force and motion?

Back

A force can cause an object to move, and if the forces are unbalanced, motion will occur.

Front

What is the difference between power and work?

Back

Power is the rate at which work is done, while work is the total energy transferred by a force.

Front

Can balanced forces cause motion?

Back

No, balanced forces do not cause motion; they keep an object at rest or moving at a constant speed.

Front

What is an example of a machine?

Back

Examples of machines include levers, pulleys, and inclined planes.
