Force & 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 the net force on an object is 0N, what can we say about the forces acting on it?

Back

The forces acting on the object are balanced.

Front

What happens to an object when an unbalanced force acts on it?

Back

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

Front

What is the direction of motion if a force is applied to the left?

Back

The object will move to the left.

Front

What is the effect of balanced forces on a moving object?

Back

Balanced forces do not change the motion of a moving object; it continues to move at a constant speed in a straight line.

Front

What is an example of an unbalanced force in everyday life?

Back

A car accelerating when the driver presses the gas pedal is an example of an unbalanced force.

Front

How can you determine the net force when multiple forces are acting on an object?

Back

Add the forces acting in one direction and subtract the forces acting in the opposite direction.

Front

What does it mean if a model shows forces acting on an object but not their actual amounts?

Back

It means the model illustrates the direction and relative strength of forces but does not quantify them.
