What do a falling basketball a moving car and a trophy on a shelf all have in common?
They all have mechanical energy.
The speed of a ball falling from a high shelf to the floor is 9.8 m sec What is its velocity?
vf = sqrt(vo2 + 2a(X - Xo)) in this casevf = sqrt(0+2*9.8(Height of shelf)
Does a book sitting on a self have potential energy?
its physics term for the fact that it is not in motion (kinetic energy) but it is above the ground, so at any moment it could "potentially" have kinetic energy by falling to the floor.
Can an object have energy when it is at rest?
Sure. When a 6-kg bowling ball is resting on a shelf that's 2 meters off the floor, it has 12 joules of gravitational potential energy referenced to the floor.
If gravity is the only force present what is the total mechanical energy of a book falling off a shelf at a time when its potential energy is 50 J and its kinetic energy is 60 J?

Does a book falling from a shelf have gravitational energy?
Yes; while on the shelf it has potential energy due to gravity of mgh where m = mass and g =gravity acceleration and h is height fom floor. As it falls its potential energy is converted to kinetic energy mv squared/2 where v = velocity
Is a book falling from a book shelf kinetic or potential?
When a book is falling from a bookshelf, it is in a state of kinetic energy because it is in motion. Potential energy arises when the book is stationary on the shelf due to its height above the ground.

They all have mechanical energy.
What are the lyrics to bye bye birdie?
Birdie Birdie, sitting on my shelf, Birdie Birdie, falling off my shelf, Birdie Birdie hitting the floor, Birdie Birdie is no more
What experiment can you build with elastic energy mechanicl energy and gravitational potential energy?
A bowling ball rolling off a shelf and falling down onto a trampoline.

Is a book on a shelf potential energy?
Yes it is. Because it has the POTENTIAL of falling off. Very simple physics, learned that in 6th grade.
When is the potential energy of one-kilogram box of chocolates hidden on a shelf in the pantry 2 meters above the floor?
19.6
What kinda of energy is a box of matches?
A box of matches on a high shelf has gravitational potential energy.A box of matches falling from the high shelf has kinetic energy.A box of matches on fire has heat, sound and light energy.A box of matches on its own has chemical potential energy.
