Balanced, Unbalanced & Net Force

Front

What is a balanced force?

Back

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

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

What is net force?

Back

Net force is the overall force acting on an object after all the individual forces are combined.

Front

If two forces act in opposite directions, how do you find the net force?

Back

You subtract the smaller force from the larger force.

Front

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

Back

The object will remain at rest or continue to move at a constant speed in a straight line.

Front

What direction will an object move if the net force is unbalanced?

Back

The object will move in the direction of the greater force.

Front

If a car is rolling faster down a ramp, what can we infer about the forces acting on it?

Back

The forces acting on the car are unbalanced.

Front

What is the effect of friction on motion?

Back

Friction opposes motion, acting in the opposite direction to the movement of an object.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its motion.
