Agolf ball when either its speed or direction changes.

Hey there!

Your answer should be "accelerates."

A gold ball accelerates when either it's speed or direction changes.
This means that the golf ball moves in a high speed no matter how the direction or speed changes.

Hope this helps you.
Have a great day!

Accelerates is your answer.

Hope this helps.

Kinetic energy = 1/2mv^2. since the mass is constant we can form a ratio of it's kinetic energy at 60 divided by that at 30 to see ke(60)/ke(30) = +(60^2)/30^2). this may be said to 300% increase.
