The Nature of Energy Flashcards
1
Q
Energy
A
the capacity to do work or transfer heat
2
Q
Work
A
the transferred energy when a force is exerted on an object causing a displacement of that object
3
Q
Heat
A
energy used to increase an object’s temperature
4
Q
Force
A
any push or pull exerted on an object
5
Q
Equation for work
A
w = F (force exerted on object) x d (distance)
6
Q
Energy of motion; equation
A
kinetic energy; Ek = 1/2mv^2
7
Q
If an object’s velocity and mass increases, what happens to the kinetic energy?
A
it increases
8
Q
potential energy/electrostatic potential energy
A
stored energy created from attractions & repulsions an object experiences in relation to other objects; interactions between charged particles
