Static friction
potential energy and kenetic energy
You are using chemical energy produced in your muscles to lift a weight against gravity, which means the weight gains gravitational potential energy
Gravity holds you to the Earth, so if it holds you, it holds the chair and can hold you to the chair...
When you sit in a chair your gravitational weight down on the chair and the chair pushes up to counteract
its like your sitting in a chair potential then u get up and do something like move the chair kinetic
ex.ball in the table ,bag in the chair, bottle in the ground
Beginning with its potential energy, which is converted to kinetic energy when it falls
Static friction
potential energy and kenetic energy
dont know
You are using chemical energy produced in your muscles to lift a weight against gravity, which means the weight gains gravitational potential energy
Chemical energy from the person's muscles is turned into potential energy.
I am not sitting in a chair!
Broked is not a word - She broked the chair she was sitting on. Use broken - She had broken the chair she was sitting on. Or use broke - She broke the chair she was sitting on. Or use breaking - She was breaking the chair she was sitting on.
without friction most things become impossible.
Everywhere, for example sitting on your chair, walking, using a mode of transport.
