Force and Motion

Learn about Newton's laws of motion and simple machines!

What Will I Learn?

You may not think that motion or simple machines are important, but trust me, they are! The laws of motion and simple machines are everywhere around us! It's nearly impossible to go through a day without using simple machines and motion. For example, how did you get to school today? If you said car, than you used the simple machine WHEEL AND AXLE. Also, you move every day, so without motion and gravity, we would be stuck.

What are Newton's laws of motion? Why are they so important?

1st law of motion: Objects in motion will stay in motion unless acted upon by an outside force.

2nd law of motion: force equals mass times acceleration. The greater the force, the greater the speed.

3rd law of motion: For every action, there is an equal and opposite reaction.
