An object with uniform circular motion travels in a circle with a constant speed. If you were to glue a golf ball to

a string & swing it in a circle over your head, the string keeps the ball traveling in a circle, while centrifugal force

pushes the ball outward. For the ball to keep moving in a circle, it's is constantly changing,

How do we know of the golf ball is accelerating?

It's speed changes all the time

it's direction changes all the time

Both A & B

The golf ball isn t accelerating

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.
