NEETPhysicsMotion in One Dimension

Is the following statement true or false: "A particle in one-dimensional motion with a positive value of acceleration must be speeding up."

Options

  1. ATrue, because positive acceleration always implies speeding up, as the velocity is increasing.
  2. BTrue, because positive acceleration always implies slowing down, as the velocity is decreasing.
  3. CFalse, because positive acceleration can result in either speeding up or slowing down, depending on the initia
  4. DFalse, because acceleration does not affect speed or velocity.

Correct answer

C. False, because positive acceleration can result in either speeding up or slowing down, depending on the initia

Step-by-step solution

Correct Option is : (C) False, because positive acceleration can result in either speeding up or slowing down, depending on the initial velocity.
