the rate of change in the velocity of a body
Earth being a massive body attracts every other massive body. This force of attraction is named as weight of the body. But force is equated to the expression m*a Here m is the mass of the body and a is the acceleration. So the general a is to be replaced by g a symbol meant for the acceleration due to gravity. Its average value is 9.8 m/s2
acceleration is the rate of change of velocity as a function of time
Yes. If a body has a constant velocity there is no acceleration, but if the velocity is changing there is acceleration present.
force acting on unit mass of body is the acceleration of that body.
Mass measures the body's resistance to acceleration.
The acceleration is zero for a body having constant velocity.
a body is accelerating if it is speeding up faster and faster. Acceleration is the change in velocity. or the change in speed. Slowing down is also acceleration but it is negative acceleration or de acceleration.
Average acceleration is the average of the accelerations acquired in the whole journey by a body while instantaneous acceleration is the acceleration of the body at any particular instant of time.
No a boday while rest cannot be in acceleration because of the momentum of the body ...........................
if body is free falling state its acceleration would be 9.8meter/second2
acceleration of free fallilng body near to earth.
Acceleration becomes zero.
