Velocity and Acceleration

Question 1

Accelration

Answer 1

when an object speeds or slows down, acceleration is a measure. of how fast the velocity changes.

Question 2

Equation

Answer 2

Acceleration=change in velocity/time taken

Question 3

deceleration

Answer 3

If the acceleration is negative it means that the velocity is decreasing i.e. a.

If speed of moving object stays constant, but direction changes, this is aacceleration.
