An object at rest will stay at rest unless a force moves it. An object in motion will stay in motion unless a force stops it.This is also called ¨INERTIA¨
Newtons first law of motion
The book is at rest on the table unless an outside force knocks it off.
When I knock the book off of the table it falls on the floor. The stopping force is the floor.
The movement (acceleration) of an object depends on 2 factors.FORCE & MASS This relationship can be expressed as a formula: F= M X A
Newtons Second law of motion
I need to push this box into the house. My force will depend on the mass of the box and my acceleration.
The mass of the box is 60kg. If I accelerate at 3000 newtons then the force I need will be 50 m/s².
