force applied on a moving object..a) bring it to rest b.) change the direction c.) increases the speed d.) all of these
Answers
Answer:
the answer is option (d) i.e all of the above
Forces include gravity, friction, and applied force. Force causes changes in the speed or direction of motion. These changes are called acceleration.
An object will continue to move until a force slows or stops it. The force stopping the object's motion might be an obvious one - the ground! Friction is a force that slows or stops motion. Friction is the resistance to motion created by two objects rubbing against each other (the sled and the snow, for instance).

Again, the first step is to set the equations for energy -- this time kinetic energy -- and work equal to each other and solve for force. W = KE is F × d = 0.5 × m × v^2, so F = (0.5 × m × v^2) ÷ d.
