You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?
