Question

The area under acceleration-time graph gives

• A. change in acceleration
• B. change in velocity.
• C. change in displacement.
• D. change in deceleration

Answer 1

The correct option is B change in velocity.

$a=dv/dt$

${\int }_{v_1}^{v_2}dv={\int }_{t_1}^{t_2}adt$

Area under the acceleration time gives the change in velocity.
