According to newton's first law, an object in motion will stay in motion unless:

unless acted upon by an unbalanced force.

Explanation:

If a ball is rolling, it will continue to roll forever, unless it is acted upon by an unbalanced force. For example, the friction of the floor it's rolling on slows it down. The density of the air hitting it also slows it down.

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary
