Reece Witcher Work ● Work is equal to the force times the distance an object travels ○ W=F∗s ● However work is only done if the force is parallel to the displacement ○ W=F∗scosθ ● Work is a scalar quantity. So it is dot product of the Force and displacement ● Total work is the net force multiplied by the displacement ○ W=F(net)∗scosθ ● Work is equal to the change in energy ○ W=Δ E of a system ○ This includes all forms of energy an object possesses Energy ● Kinetic Energy is equal to the mass of the objects multiplied by its velocity squared ○ KineticEnergy=1/2m∗v ○ This quantity is always a positive or zero value ● Ener
