- The flag is moving to the right.
- The boy skating is moving to the right.
- The horse is not moving so it's balanced.
- The basketball is moving down because there is more force pulling down on the ball.

It is an unbalanced force because there are different forces pushing and pulling in the same direction. It is accelerating to the left.

- The object that created this graph must have been accelerating slightly and then going at a constant pace then started to accelerate again. After the last acceleration the speed started to go down.
- the runner's speed at 20 seconds is 0.5m/sec
- This graph mostly shows unbalanced forces but between 20 and 40 seconds it is actually a balanced force.

Object A is a balanced force and is going at a constant speed. Object A started at a constant speed and then accelerated. Object A is a balanced force and Object B is an unbalanced force

The boys playing tug of war represent a balanced force. They have two equal forces pulling on either side of the rope. The car crash is an unbalanced force. The tree is exerting a force stronger than than that of the car so the car's hood got crumpled in.

- 2sec/meter
- When a ball is sitting still on the tennis court and then I hit it so it accelerated and rolled away.This is an example of Newton's first law.

- 0.3minutes/km
- If a bowling ball were to be kicked you would have to apply more force than you would for a regular soccer ball. This is because the bowling ball has more mass than the soccer ball.
