Newtons 3 Laws

law of inertia, force & acceleration, and action/reaction

Newtons Law of Inertia

Newtons first law is the law of inertia. An object at rest will stay at rest unless acted on by an unbalanced force. Because of inertia, an object will keep doing what it's doing unless forces become unbalanced.

Newtons law of inertia most definitely occurs to everyday life. A few examples are, Newtons first law is the law of inertia. An object at rest will stay at rest unless acted on by an unbalanced force. Because of inertia, an object will keep doing what it's doing unless forces become unbalanced. Also, Lets say a football player was running down the field with the ball, he is the balanced force that will continue to move until a unbalanced force stops it. Well another guy is the unbalanced force so he is going to tackle the unbalanced force to stop him from getting any further down the field.

Newtons law of Force & Acceleration

Acceleration is the rate of which velocity changes over time. Newtons 2nd law of motion states that the acceleration of an objects speed, direction, or both. An objects acceleration is in the direction of the net force.

For example, it's easier to push an empty shopping cart than a full one. Why? Because the full cart has more mass than the empty one. This means more force is required to push the full one.

Another example is that if you use the same force to push a car and a truck, the car will accelerate more than the truck because the truck has a lot more mass than the car does.

Newtons law of Action/Reaction

For every action, there is an equal & opposite reaction. All forces act in pairs!

Some real life examples are, when you let air fly out of the balloon, the reaction is that the balloon flies up.

Another example is, When you dive off of a diving board, you press on the springboard, the board pushes you back up, forcing you into the air.
