Force & Net Force

Front

What is force?

Back

A push or pull on an object that can cause it to move, change direction, or change speed.

Front

What is net force?

Back

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

Front

What is a balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Forces that are not equal and opposite, causing a change in motion.

Front

If two forces of 50 N and 30 N act in the same direction, what is the net force?

Back

80 N in the same direction.

Front

If two forces of 50 N and 30 N act in opposite directions, what is the net force?

Back

20 N in the direction of the larger force.

Front

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

Back

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

Front

In a tug-of-war, if one team pulls with 400 N and the other with 250 N, which team wins?

Back

The team pulling with 400 N wins.

Front

What is the formula for calculating net force?

Back

Net Force = Total Forces in One Direction - Total Forces in Opposite Direction.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.
