5. Acceleration is a change in position and speed.

True or false

I think False

Please help me.

false because acceleration is the time rate of change of velocity.

speed is scalar and acceleration vector it cannot be ture.

Thx. :)

You are correct, the statement is false. Acceleration is a change in velocity, not just in position and speed. Velocity is a vector quantity that includes both speed (magnitude) and direction. Acceleration, on the other hand, refers to the rate of change of velocity. It can involve changes in speed, direction, or both. To confirm this, you can look up the definition of acceleration in a physics textbook or search online for reliable sources.
