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 does it mean for forces to be balanced?

Back

Forces are balanced when they are equal in size and opposite in direction, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Forces are unbalanced when they are not equal, causing a change in motion.

Front

If an object is at rest and the forces acting on it are balanced, what will happen?

Back

The object will remain at rest.

Front

If an object is moving at a constant speed and the forces acting on it are balanced, what will happen?

Back

The object will continue to move at that constant speed.

Front

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

Back

The object will not accelerate; it will either remain at rest or continue moving at a constant speed.

Front

What is the formula for calculating net force?

Back

Net Force = Force applied - Force opposing.

Front

If a bat exerts a force of 1200 N and a ball exerts a force of 400 N in the opposite direction, what is the net force?

Back

800 N in the direction of the bat's force.

Front

What is an example of an unbalanced force?

Back

A car accelerating when the driver presses the gas pedal.
