Forces
Storyboard Text
- Gravity
- What the heck, isn't Gravity supposed to kick in yet?
- Friction
- Oh no! There goes the puck! Friction please help me now!
- Elastic Force
- HaHa. He doesn't even realize I shot a band at him.
- Gravity is an attractive force that pulls objects to one another. Gravity helps people stay on the ground and not float into space such as above. An object as large as the Earth, it causes humans stay on the ground and attracts them towards the center of the Earth.
- Magnetism
- I'm sorry I can't help it. I'm like a magnet or something
- Friction is the force that causes objects to stop because they rub against each other and resist. In hockey, without friction, the puck would continue to slide because of Newton's First Law of Motion. But, the puck rubs the ice causing it to stop eventually.
- Gravity
- Why is the football going down so fast?
- I guess the force of gravity is too strong
- When an elastic material is stretched, it builds up counter force. When let go, it shoots foward quickly because of all the force generated. The amount of force depends on how much the material is stretched.
- Friction
- Magnetism is the force that is exerted by magnets when they either repel or attract each other. In this example, the person is attracting others because the force is too strong to fight it. Magnetism is caused by the motion of electric charges.
- Let us Go!
- The Force of Gravity is always constant and gravity is what helps the ball come down and into the receiver's hands. If gravity is too strong, the ball will go towards the ground right away. If too little, the ball is will be in the air too long. Strength of gravity depends on how large the planet is and the distance from the ground.
- Friction occurs in everyday life and driving is no exception. When you are normally driving, friction occurs between the wheels and the surface the vehicle is traversing over. Static Friction for example, is shown when the wheels push against the pavement to move, but there is no sliding of the tires against the pavement.
- Thank Goodness for friction. Or else I would have ran into that sign.
