Force & Net Force

Front

What is force?

Back

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

Front

What is net force?

Back

The total force acting on an object after 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 an object is at rest and the net force is zero, what can we say about the forces acting on it?

Back

The forces are balanced.

Front

What happens to an object when the net force acting on it is not zero?

Back

The object will accelerate in the direction of the net force.

Front

What is friction?

Back

A force that opposes the motion of an object, acting in the opposite direction of the movement.

Front

How does mass affect the force needed to move an object?

Back

The greater the mass of an object, the more force is needed to move it.

Front

What is inertia?

Back

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

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, Force = Mass x Acceleration (F = ma).
