What is mechanical work:
Energy transferred from one object to another via a force is an example of mechanical work.

Why could a object project upwards pick all answers:
The object's energy is initially in the kinetic store as it moves upwards
Once the object reaches its highest point, all of its energy is in the gravitational potential store.
As the object falls again, energy transfers from the gravitational potential store to the kinetic store.
The object's energy is slowly transferred from the kinetic store to the gravitational potential store as it slows down and climbs higher.
What energy is tranfered when boiling a kettle:
Thermal to kinetic
Thermal to chemical
Thermal to neuclear
What happens when an object is acceleated by a constant force pick that is approate :
Work is done by a force on an object.
The work is converted to chemical
The work is converted to mechical
This work is converted to the object's kinetic store.
What happens when a car pushes the breakes:
The brakes do work slowing the car down. During this process, energy is dissipated (lost) through heat and sound.
To begin with, the vehicle's energy is in the kinetic store.
The brakes slowing the car down. During this process beacuse of the fiction
What happens when an object hitts another object pick all that apparate:
The object's energy is in the kinetic store at the start because it is moving.
When the object collides with the obstacle, energy is converted to:
The kinetic store of the obstacle (making it move). The thermal store of the object and the obstacle (the particles in the object and the obstacle vibrate more).
Some energy remains in the object's kinetic store as it moves away after the collision.
I don't know
Energy can be created and destroyted:
True
False
