#### Storyboard Text

• My name is Dan and I will be demonstrating Newton´s Laws ﻿
• The first law states, an object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an outside force.
• Lets say I have a ball. It is not in motion.
• However, if I kick the ball it will be in motion untill a force, like my foot acts on it.﻿
• The second law law states, the acceleration of an object depends on the mass of the object and the size of the net force applied.
• ﻿﻿Pretend that you have 2 wagons, one with rocks and one with feathers. You would only need to exert a small force on the wagon with feathers to move it and would need a larger force on the one with rocks to move it.
• If you apply the same force, the greater the mass, the smaller the acceleration. The one with feathers would move faster.
• Also Newton´s 3rd and final law states, when a force is applied to an object, the object exerts an equal force in the opposite direction. ﻿
• ﻿Its like when you bounce a ball to the ground and it bounces back up to you! The ball pushes on the ground and so the ground pushes the ball back up.
• ﻿(Yawn) Im getting tired. See you later! Bye!
