Characteristics
Acceleration is a vector quantity.
Formula −
a = ΔvΔt = dvdt
Unit of acceleration is ms-2
Dimension of acceleration is [LT-1]
Acceleration has sign −
When there is increase in velocity, acceleration is positive.
When there is decrease in velocity, acceleration is negative.
Observe the following diagram to understand sign of acceleration −
Suppose a ball is rolling over the ramp in the figure.
