Potential energy, electric potential energy, kinetic energy, etc. are some examples of different types of energy. Kinetic energy comes when the object starts moving. This energy is due to motion. ... Sample Problems. Question 1: A ball has a mass of 2Kg, suppose it travels at 10m/s. Find the kinetic energy possessed by it. Answer:
Problems from IIT JEE. Problem (JEE Mains 2022): A body of mass 8 kg and another of mass 2 kg are moving with equal kinetic energy. The ratio of their respective momenta will be 1:1; 2:1; 1:4; 4:1; Problem (JEE Mains 2003): A spring of spring constant $5\times10^3$ N/m is stretched initially by 5 cm from the unstretched position. Then the work required to stretch it further by another 5 cm is
Kinetic Energy is directly proportional to the object's mass and its velocity square, which is K.E. = 1/2*m*v². Where m is the mass in kilograms, v is the velocity in m/s. The SI unit of measurement of Kinetic Energy is the same as Potential Energy which is kg. m 2 /s 2 or Joule(J). The Relation Between Potential Energy and Kinetic Energy
Kinetic and Potential Energy Worksheet Name _____ Classify the following as a type of potential energy or kinetic energy (use the letters K or P) ... Solve the following word problems using the kinetic and potential energy formulas (Be sure to show your work!) Formulas: KE = 0.5 ·m· v2 OR PE = m·g·h
Potential energy of the ball = Final gain in the kinetic energy P= m.g.h m= 1kg, h= 10m, g= 9.8m/sec 2 P= 1× 10× 9.8 P= 98 Joule Therefore, the final gain in kinetic energy is 98 Joules. K.E= 98 Joule. Question 8: Explain the existence of potential energy, a. Due to its position b. Due to the state in which the object is. Potential energy can ...
A rock sitting on the edge of a cliff. If the rock falls, the potential energy will be converted to kinetic energy, as the rock will be moving. A stretched elastic string in a longbow. What are 4 types of kinetic energy? There are five main types of kinetic energy: radiant, thermal, sound, electrical, and mechanical.

KE = 1/2 m v2 OR GPE = mgh 1. You serve a volleyball with a mass of 2.1 kg. The ball leaves your hand with a speed of 30 m/s. The ball has _____ energy.
Solved Example Problems for Potential Energy Example 4.8. An object of mass 2 kg is taken to a height 5 m from the ground g = 10ms-2 . a. Calculate the potential energy stored in the object. ... When the object is just about to hit the ground, the total energy is completely kinetic and the potential energy, U = 0. Example 4.14.
This final example uses the conservation of energy. In questions like these, use both the kinetic energy and the potential energy of an object to solve the problem. It is a good idea to show your working at each step of the problem as you rearrange the equation. Example: A lump of ice falls from an aeroplane as it comes in to land. If the
