Question

what is acceleration

Answer 1

Acceleration is change in velocity per unit time . a=dv/dt. a=d(dx/dt)/dr. =d2(x)/dt2

Answer 2

HEY MATE...!!!✌

➤ Acceleration

• Acceleration is the  rate of change of velocity with time.
• It  is defined as change of velocity of body per unit time.
• SI unit of acceleration is m/s²
• It is Vector Quantity.
• Acceleration = Change in velocity / time

       = Final velocity - Initial velocity / time

       = v - u / t

➤ Types of Acceleration

1. Uniform Acceleration

If the velocity changes in equal amounts in equal time of intervals and the object travels in a straight line than the uniform acceleration take place.

2. Non-uniform Acceleration

If the velocity changes in an equal amount in unequal intervals of time and object travels in straight line then non uniform acceleration take place.

-: Additional Information :-

♦ Zero Acceleration :-  

• If the change in velocity is zero that is either object is at rest or moving with uniform velocity than zero acceleration will take place.

♦ Positive Acceleration :-  

• When velocity of a body increases then positive acceleration take place.
• i.e v > u

♦ Negative Acceleration :-  

• When velocity of a body decreases the negative acceleration take place.
• It is in the opposite direction of velocity.
• i.e v < u
