Newton's Laws
Storyboard Text
- Newton's 1st Law demonstrates that an object in motion remains in motion and an object at rest remains at rest, unless it is acted upon by an unbalanced force.The ball was at rest before Austin threw it which forced the ball forward towards Finn and it will remain in motion until some force acts upon it, which in this case is air resistance, until it hits Finn's hands with a force of 0.53 Newtons because the ball has a mass of 56.42 g and it is accelerated towards Finn at 5/0.73² m/s² = 9.4 m/s².
- Newton's 2nd Law tells us that the force acting on an object is equal to the mass of the object times the acceleration.If we drop a ball straight down, we can calculate the force applied to the ball by measuring the acceleration and mass of the tennis ball. For example, if the ball has a mass of 56.42 g and it is accelerated towards the ground at 9.8 m/s² then the force acting on the tennis ball is 0.55 Newtons.
- Newton's 3rd Law states that every action has an equal and opposite reaction.The ball was accelerated forward by Fin in the direction of the wall. The force of the ball is not strong enough to penetrate through the wall, so the ball bounces back in the direction it came from when the wall pushes back on the ball.
