Friction practice e answers
WebUsing subscripts 1 and 2 to represent initial and final energy, this law is expressed as. K E 1 + P E 1 = K E 2 + P E 2. Either side equals the total mechanical energy. The phrase in a closed system means we are assuming no energy is lost to the surroundings due to friction and air resistance. Webstatic friction c. kinetic friction d. sliding friction e. none of these Static Friction is non moving friction. Friction opposes the attempted motion. 4) If the net force acting on a ball is directed to the left, then the direction of the acceleration of the ball is a. Down due to gravity. b. To the right due to Newton’s 3rd Law. c.
