Forces And Energy
Forces
There are three types of forces when a soccer ball is in the air after its been kicked:
Gravity
Drag
Lift
Friction
Our experiment was to see if different types of footwear would
affect how far we could kick a soccer ball.
Shoes are made to do different things, so we are seeing if there are differences
in distance when we kick using different footwear.
The types of footwear we used were soccer shoes, sports shoes and bare feet.
The people in our group are: Akaash,Jego,Kelvin,Kian and Rico.
Gravity is the force when something is pulled down back onto the earth. Everything that goes up must come down, this is because of gravitational pull. When we kick the soccer ball up into the air, the soccer ball slowly comes down, the ball comes down because of gravity.
Drag is the force that is opposite to the way the ball is heading. If the soccer ball is kicked towards the right side, the drag will be on the left side, pushing the ball back. the drag depends on the shape and size of an object.
Lift is the force that makes the ball spin, the lift depends on where you kick the soccer ball.

Energy
The energy that exists when you kick a soccer ball are
Kinetic
Potential
Elasticity
Thermal
When a ball is ready to be kicked,it has potential energy, when the ball is kicked the potential energy is turned to kinetic energy.
Kinetic Energy is when you kick the ball, your leg puts kinetic energy into the ball. When you kick a soccer ball and the ball moves the ball has kinetic as well as potential energy.
When someone kicks the ball and it goes high into the air, when it comes back down, it hits the ground hard and the ball deforms, then it goes back to its original shape, also when someone kicks the ball the ball deforms, then it comes back to shape again. This is elastic energy.
There is a little bit of heat given out when someone kicks the ball. This is thermal energy.
