How does friction, acceleration, speed and net force relate to each other? Explain.

Explanation:Explanation: Newton's 2nd law states acceleration is proportional to the net force acting on an object. ... This means if friction is present, it counteracts and cancels some of the force causing the motion (if the object is being accelerated). That means a reduced net force and a smaller acceleration

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
