This law states that an object will maintain its motion (at rest, or constant velocity) until it is acted upon by an unbalancing force (which accelerates the object).

In the video below you will see a stationary cart and my hand, the unbalanced force, pulls it back and pushes it forward. This demonstrates Newton's first law of motion because the cart would keep moving with inertia, but friction stopped it.

This law states that a net force that acts on an object causes the object to accelerate in the direction of the net force. This law is represented by the equation F=ma where F is the force, M is mass, and A is the acceleration.

In the video below you will see a small piece of wood being hit forward and accelerate while a bigger weight is hit with the same force but is much harder to accelerate. This demonstrates Newton's second law of motion because it represents how the mass and acceleration are related inversely, where more mass equals less acceleration.]]> 2019-05-02 14:51:47 UTC https://padlet.com/macgjm397/f1bfjtlm9kvn/wish/356235509 Third Law of Motion macgjm397 https://padlet.com/macgjm397/f1bfjtlm9kvn/wish/356235578 Newton's third law is the law of action and reaction. This law states that for every reaction there is an equal and opposite reaction (of equal force in the opposite direction.)

In the video below you will see two carts with equal force crash into each other. They both go back in the opposite direction after they collide. This demonstrates Newton's third law of motion because it represents that every action (the two cars colliding) there is an equal and opposite reaction (the cars moving backward, in the opposite direction.) ]]> 2019-05-02 14:51:54 UTC https://padlet.com/macgjm397/f1bfjtlm9kvn/wish/356235578
