Some less obvious forces are friction, gravity and air resistance. Some more obvious forces might be pushes, kicks or pulls. 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.ĭescribe some different forces that act upon objects. This might be important if you were trying to step off a boat onto a dock. Newton’s laws of motion are helpful when making predictions of motion. Why do people need to know about Newton’s Laws of Motion? ANSWER You would need much more force to push a car the same distance as a shopping cart. One example is pushing a car or pushing a shopping cart. What would be an example of this law in action? ANSWER Newton’s second law of motion states that larger things need more force to move them than lighter things. If a ball is still, it will remain still until a force, such as a kick, makes it move. After Video Newton’s first law of motion states that an object's motion remains the same unless a force acts upon it.They need to know how different materials move and interact with each other.
Many engineers design different things that move. Why is it important for people to learn about motion and forces? ANSWERĭifferent careers would require people to know about motion and forces. 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. Some examples of the powerful force of moving water are tsunamis and flash floods.Īir moving can be a gentle force. The movement of water can be a very powerful force. If you use more force on the heavier object than the lighter object, you might be able to throw them the same distance. Heavy objects don’t go as far as lighter objects when using the same amount of force. What happens when you throw something heavy vs. 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. If a car rear ends another, the first car will be pushed forward, while the second would slow down. It depends on if the objects are moving in opposite directions or the same direction. What happens when two objects collide? ANSWER Some forces are pushes, pulls, kicks, wind and water. Before Video What are some forces that cause objects to move? ANSWER.
