3.2 a) Not for acceleration b) Acceleration because you have to stop it for it to turn properly Best Times Position: 0 Velocity: 10.3 Acceleration: Couldn't get it 4.2 a)The forces are acting upon it is certain directions pulling it or pushing it in some direction inbetween

4.3 a) Toward the cursor if attraction and away from the cursor if repulsion. The cursor increased the aceleration of the ball. b) No because it is acceleration not velocity. Best Times Attraction: 2.04 Repulsion: 1.4

3.2 a) He found that the steeper an incline is, the more gravity affects it, and the more acceleration it gets due to gravity.
