Question

Can a body has acceleration without the change of magnitude

Answer 1

Magnitude , may be , here is momentum .
The answer is no , Body can't acceleration , without change in Momentum .

; Momentum = Mass × Velocity .

; Acceleration is the change in Velocity of respect with Time .

If Velocity changes , then , Momentum or Magnitude is also changes .



But , if the Magnitude , here , is force , then .
Yes , Change in Magnitude = Change in Acceleration .
