Kinetic Energy

Motion energy is properly called kinetic energy; it is proportional to the mass of the moving object and grows with the square of its speed (velocity). You can calculate the kinetic energy of an object by using the following equation:

$$KE=\frac{1}{2}mv^2$$  

Using this equation, you will recognize that as the mass (m) or velocity (v) of an increases or decreases, kinetic energy of the object also changes in a predictable manner.

$$KE=\frac{1}{2}mv^2$$  

Based on the kinetic energy equation, which object has more kinetic energy? Assume both balls are moving at the same speed (velocity).

$$KE=\frac{1}{2}mv^2$$  

Based on the kinetic energy equation, which object has more kinetic energy? Assume both balls have the same mass.

$$KE=\frac{1}{2}mv^2$$  

Based on the kinetic energy equation, which object has more kinetic energy? Assume both balls have the same mass.

$$KE=\frac{1}{2}mv^2$$  

Based on the kinetic energy equation, which object has more kinetic energy? Assume both balls are moving at the same speed (velocity).

$$KE=\frac{1}{2}mv^2$$  

According to the equation, you have to square the velocity (speed) of the object in order to calculate its kinetic energy. This simply means you multiply the number by itself.

If the velocity (speed) of an object is 2, what is the result when you square the velocity?

$$KE=\frac{1}{2}mv^2$$  

According to the equation, you have to square the velocity (speed) of the object in order to calculate its kinetic energy. This simply means you multiply the number by itself.

If the velocity (speed) of an object is 3, what is the result when you square the velocity?

$$KE=\frac{1}{2}mv^2$$  

According to the equation, you have to square the velocity (speed) of the object in order to calculate its kinetic energy. This simply means you multiply the number by itself.

If the velocity (speed) of an object is 4, what is the result when you square the velocity?

$$KE=\frac{1}{2}mv^2$$  

According to the equation, you have to square the velocity (speed) of the object in order to calculate its kinetic energy. This simply means you multiply the number by itself.

If the velocity (speed) of an object is 10, what is the result when you square the velocity?

$$KE=\frac{1}{2}mv^2$$  

According to the equation, you have to multiply $$\frac{1}{2}$$  by an an object's mass (kg) and it its velocity squared.

What decimal value is equivalent to $$\frac{1}{2}$$  ?
