• Newton's First Law
• Motion is the phenomenon in which an object changes its position.
• It also states that the ball will stay in motion until an unbalanced force acts on it.﻿
• Newton's first law states that this ball will stay here until another force affects it.
• An unbalance force could be me kicking the ball.﻿
• Newton's first law is also known as the law of inertia, inertia describes how much an object like my soccer ball will resist change to the motion of an object.
• Newton's Second Law
• Things become harder to accelerate when they have larger mass, mass is how much matter an object has this is why its easier to move a soccer ball than a goal.
• Acceleration is the increase or rate of the speed of something like a soccer ball. ﻿
• Newton's second law states that when a force is applied to an action it causes the object to accelerate.﻿
• Eventually no matter how hard I kick this soccer ball it will stop because of the friction on the ground and the air.
• When I kick the ball it creates speed and velocity.
• Newton's second law also has many other forms to measure it like speed and velocity
• Speed is the just the rate at which something is traveling, velocity is very similar to this but it includes the direction the object is going.
• To do this we can find the distance the ball traveled and the time it took to stop.
• The formula for this is speed = distance over time, to make this easier we can use a reference point such as the goal or a nearby tree.
• But what if you wanted to calculate the speed of the soccer ball.
• Displacement
• Possible directions could be North, East, South, and West.
• Displacement is another way to measure only the distance and direction.
• Newton's Third Law
• Since my head is applying force to the ball the ball applies the same amount of force back, this is why sometimes after I hit the ball my head hurts.
• This is shown when I use my head to hit the ball.
• Finally newton's third law states that for every action there is and equal and opposite reaction.
