1. The more velocity an object has the harder it is to slow
it down, speed it up, or turn it.

The more velocity an object has the harder it is to slow it down

Explanation:

slow it down

it is easily magnetized.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
