1) Can there be a non-zero acceleration when the velocity is zero? Explain and give an example.

2) can there be a zero acceleration and velocity is not zero? explain and give an example.

Expert Solution

1) yes it is possible that there is non zero acceleration when velocity is zero . Take an example of ball thrown vertically upwards, it undergoes a motion under the influence of constant acceleration , that is Acceleration due to gravity pointing vertically downwards. At the highest point of motion , the ball comes to momentarily rest and at this point velocity is zero but acceleration is not zero and has a constant magnitude of 9.8 m/s^2 acting in downward direction.

2) yes it is possible that an object has zero acceleration but has non zero velocity. Example, think of a car moving on a straight road at a constant speed of 50 mph , in this case , its speed is not changing with respect to time , thus it is moving with non zero velocity but zero acceleration.

Choices: True or False. If velocity is zero then acceleration must be zero too. If speed is constant then acceleration is zero. If velocity is constant then speed must be constant too. If speed changes then velocity must change too. Object slows down if it's acceleration is negative. If speed is constant then velocity must be constant too.
