The sum (net) forces show that the object will

• accelerate to the left

• no change in motion

• accelerate to the right

Forces that are acting on an object but cancel each other out because they are going in opposite directions are called

• unbalanced forces

• balanced forces

• friction

• gravity

If the sum of the forces acting on an object add up to more than 0, the forces are

• equal

• opposite

• balanced

• unbalanced

What happens if a force is added to an object??

• the object speeds up

• the object changes direction

• the object speeds up and changes direction

• the object speeds up or slows down and can change direction, depending how much force is added and in which direction

Unbalanced forces cause

• change in motion

• speeding up, slowing down, and/or changing direction

• acceleration

• all answers are correct

Tags

Balanced forces cause

• no motion at all

• change motion (acceleration)

• no change in motion

To get the net (sum) force of two forces that are acting on the same object but in opposite directions, you would

• get the difference between the two forces (subtract)

• add the forces together

• divide the forces

• multiply the forces

• 0 N

• 10 N

• 5 N
