Newton’s Laws of Motion

Some forces are pushes, pulls, kicks, wind and water.

It depends on if the objects are moving in opposite directions or the same direction. If a car rear ends another, the first car will be pushed forward, while the second would slow down. If two cars are moving in opposite directions toward each other and collide, they would both eventually stop, and the metal of the cars would crumple.

Heavy objects don’t go as far as lighter objects when using the same amount of force. If you use more force on the heavier object than the lighter object, you might be able to throw them the same distance.

The movement of water can be a very powerful force. Some examples of the powerful force of moving water are tsunamis and flash floods.

Air moving can be a gentle force. Some examples of a gentle force could be a paper fan moving the air around you or blowing bubbles with the air from your mouth.

Different careers would require people to know about motion and forces. Many engineers design different things that move. They need to know how different materials move and interact with each other.

If a ball is still, it will remain still until a force, such as a kick, makes it move.

One example is pushing a car or pushing a shopping cart. You would need much more force to push a car the same distance as a shopping cart.

Newton’s laws of motion are helpful when making predictions of motion. This might be important if you were trying to step off a boat onto a dock. If you push off the boat, it will move away from the dock a little, which would be important to know if you don’t want to end up in the water.

Some more obvious forces might be pushes, kicks or pulls. Some less obvious forces are friction, gravity and air resistance. All these forces affect the movement of objects.

An example of this is a ball bouncing. You throw it down on the ground with a force, and it bounces back with an equal force.

Newton’s 1st law of motion says that an object in motion stays in motion unless a force acts upon it. Even if nothing appears to stop a moving object, forces such as friction, air resistance and gravity are all acting on the object to slow it down.
