What are the two ways we can have UNBALANCED forces?
1) unequal forces in opposite directions
2) forces in same direction
1) forces in same direction
2) equal forces in opposite direction
1) unequal forces in opposite directions
2) forces in opposite directions but same sizes
1) you can't have unbalanced forces
2) forces will always balance each other out
A rightward force is applied to a car to accelerate it to the right down the sidewalk.
(anytime you see "push" or "pull" that is the same as "applied" force)
A hockey puck glides to the right across the ice at a constant speed.
(anytime you see "push" or "pull" that is the same as "applied" force)
A downward-moving skydiver who has just opened the parachute is slowing down.
