Energy transfer is the process by which energy is relocated from one system to another, for example, through the transfer of heat, work or mass transfer.

A pendulum is a simple example of energy transfer – converting potential energy to kinetic energy over and over until the small amount of energy lost to heat and air resistance causes the pendulum to come to rest.

capacity to do work. energy transfer. Noun. The conversion of one form of energy into another, or the movement of energy from one place to another. energy transformation.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

$f\alpha \frac{dp}{dt}$

⇒ $f= k \frac{dp}{dt}$

here k is the proportionality constant whose value is 1.

$f=\frac{dp}{dt}$

$f= \frac{d[mv]}{dt}$

$f= m\frac{dv}{dt} +v\frac{dm}{dt}$

$f=ma+v\frac{dm}{dt}$ [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
