Which letter shows the ball when it has the maximum potential energy? _____ 3. Which letter shows the ball when it has the least potential energy? _____ 4.
KINETIC AND POTENTIAL ENERGY WORKSHEET. Potential energy: PE = mgh Kinetic energy: KE = 1/2 m v2 Total mechanical energy: ME = PE + KE. Practice problems: 1. A baby carriage is sitting at the top of a hill that is 21 m high. The carriage with the baby weighs 12 Kg. The carriage has ____________ energy. Calculate it.
ENERGY - POTENTIAL AND KINETIC WORKSHEET 1. Determine whether the objects in the following problems have kinetic or potential energy. Then choose the correct formula to use: KE= 1/2 m v2. PE = mass x gravity (10 m/s/s) x height. Energy= joules Weight= Newton Mass= kilograms Velocity= m/s Gravity’s acceleration= (10 m/s/s
Potential and Kinetic Energy. Potential energy is stored energy. The formula for the potential energy of an object is: Ep = mgh. where m equals mass in kilograms, g is the acceleration of gravity, and h equals the height of the object. The mass.
a. What is the kinetic energy if a 1 kg ball is thrown into the air with an initial velocity of 30 m/s? b. How much potential energy does the ball have when it reaches the top of its ascent? c. How high into the air did the ball travel? 12. What is the velocity of a 500 kg elevator that has 4,000 J of energy? 13.
