Hello friend, I'm Mike the monster and today me and my friends are going to teach you about forces.
There are 6 main forces. 3 of them are non-contact forces and the other 3 are contact forces. Don't be confused we're going to tell you all about it!
But first, I'll tell you about what a force is. A force is basically a push or pull.
The first type of contact force is friction. Friction is a resistance force that occurs when two things are rubbed together. I'm making friction when I rub my foot on the ground.
Hey guys, I'm Fred and I'm going to be telling you about the first type of contact force.
Hello, I'm Eddie and I'm here to tell you about the second and third types of contact forces, Buoyancy and Elasticity.
Elasticity is a force exerted when a materiel is stretched then rebounds. A slingshot is an example of this. Elasticity is the force that lets the band stretch.
Buoyancy is a force exerted upwards by water or gas. An example is a boat floating on water. The water exerts a force on the boat that makes it float.
Hi, I'm Garland and I'm talking to you about one of the non-contact forces, gravity.
Gravity is the mutual force of attraction exerted by particles. Gravity is what keeps you and me on the ground and not floating around.
Hello, I'm Edgar and I'm going to tell you about the last two types of non-contact forces, magnetism and electricity.
Magnetic force is the attraction or repulsion that one magnet has on another, or certain materials. If a magnet was near iron the two would attract but if you put a magnet against a table, they wouldn't attract.
Electrical force is the buildup of electrons that causes oppositely charged materials to attract and objects with the same charge to repel. It's like when you rub a balloon against your hair and your hair sticks, that's cause the two objects have opposite charges.
Well there you go! Those are the six main types of forces. We had a great time telling you all about them. We hoped you had fun and learned something new!
