An object of weight 8N is moving along a horizontal plane. If the coefficient of kinetic friction is 0.25 find the friction force acting on the object.

A projectile travels above level ground. The initial vertical component of its velocity is 0.90 m/s and the initial horizontal component of its velocity is 0.60 m/s.

1) The earths gravity is pulling on you, Are you pulling on the earth Explain your reasoning with evidence. 2) Gravity is a force of attraction between objects based on their mass and their distance apart.

When Jake tosses a ball while standing still on his skateboard, he and his skateboard recoil. If he goes through the motions of tossing the ball, but doesn't toss it, his net recoil will ideally be a. almost as much as if he threw the ball b. zero c.
