Hi! I am Gravity. I exist everywhere in the Universe. I use my forces to pull objects together.
Oh no! My truck broke down and Mr. Friction is using his force between the tires of the car and the road. So, I can't push the truck.
I am Mr. Friction! The truck is very heavy so there is more force I must create to stop you from pushing the truck. You need more force against me to overcome me.
The moon is being pulled towards the Earth because the Earth is larger and has more gravity. Every single object has gravity.
Mr. Friction appears when two objects rub together. It comes in 4 different forms including sliding, fluid, static, and rolling friction. In this case, when the truck can not move it is static friction. A force greater and of more strength is needed to overcome Mr. Friction.
HAHA! I overcame you Mr. Friction! I only had to ask 3 friends for help.
The elastic force is created from the pull and release of the stretchy material. If you pull more, the elastic force when released is greater.
Hey there! I'm Stretch, I'm trying to aim this at the middle of the target. Using elastic force, I need to pull back this elastic string and when I release it, it will shoot forwards and hit the target.
The only thing that can overcome Gravity is a large amount of counter-force.
On Earth, I pull everything inwards towards the center of the Earth, like this car.
When a stronger force is used against the static friction, it overcomes Mr. Friction. Mr. Friction goes against the act of motion
AHHHH! I will be back soon! Don't forget I am everywhere even for every step you take.
Elastic force is created through many activities and actions, such as putting your hair up in an elastic band, bungee jumping or jumping on a trampoline.
See how I just hit the middle of the target? This is because I used elastic force and aimed the bow and arrow to a certain angle. This is one of the many ways elastic force helps me in my daily life.
