6. The rate at which velocity changes is called O speed
O direction
O acceleration
O displacement

Iwill give 30 points to whoever answers ! what is the formula for actual mechanical advantage and ideal mechanical advantage?

The slope of a velocity time graph over any interval of time gives the during that interval
