If a car is moving in a circle on a track, the direction of the acceleration is

If a car is moving in a circle on a track, the direction of the acceleration is . Backward on the track . Forward on the track. Toward the center of the track. No acceleration the speed is constant. If you are going around the curve on a road, the centripetal force comes from.

FORCES

FORCES. (insert scary music here). I. Forces. A push or pull on an object. It is a vector All vector rules apply Measured in Newtons (N) Why? Named after Bob Newton. B. Contact Forces. When the applied force is touching the object. Friction Tension Wind Resistance.

Calculating Work

Calculating Work. The Joule. Work is force acting over a distance, and has units equal to units of force times units of distance. With 1-dimensional constant force and distance, W = F D x The unit of work is the joule (J) = 1 N m. Constant Force.
