What is kinetic energy and derive its expression?
Derivation for the equation of Kinetic Energy: The relation connecting the initial velocity (u) and final velocity (v) of an object moving with a uniform acceleration a, and the displacement, S is. v2 – u2 = 2aS. This gives. S = ½a(v2 – u2)
What is kinetic energy derive its expression Class 11?
Kinetic energy of a body or an object is the energy that it possesses by virtue of its motion. It may also be defined as the work needed to accelerate a body of a given mass from rest to its desired velocity. Net work done = Force × Displacement. Hence derived.
What is kinetic energy expression?
Related Topics: energy E = mc2. See all related content → Translational kinetic energy of a body is equal to one-half the product of its mass, m, and the square of its velocity, v, or 1/2mv2.
What is kinetic energy derive an expression for it class 9?
Suppose a body of mass m is moving with velocity v. It is brought to rest by applying a retarding force F. Suppose it traverses a distance s before coming to rest. Kinetic energy of body, KE = Work done by retarding force to stop it.
What do you mean by kinetic energy derive an expression for the kinetic energy of an object of mass m moving with an velocity V?
W=ma*(V²-u²/2a)\=(1/2)m(V²-u²) As we assumed object at rest, u=0. W=(1/2)mV² we know that the kinetic energy of a body moving with certain velocity is equal to workdone on the object to acquire that velocity from rest. ∴K.E=1/2 mV²
What do you mean by kinetic energy derive an expression for the kinetic energy of an object of mass m moving with velocity V?
Since kinetic energy is equal to the work done on the body to change its velocity from 0 to v , we obtain: kinetic energy , Ek=21mv2.
What is kinetic energy Class 9 short answer?
Hint:Kinetic energy is the energy that an object possesses due to its motion. It is basically the energy of mass in motion.
What is kinetic energy derive an equation for it class 9?
Answer: Kinetic energy is the energy possessed by an object due to its motion is called kinetic energy. Explanation: Derivation:- v^2 – u^2 =2as , This gives = s=v^2-u^2/2as , W=ma*v^2-u^2/2a W = 1/2 mv^2 , E.K =1/2mv^2 .
What are the six types of kinetic energy?
Six types of energy include kinetic energy, potential energy, mechanical energy, chemical energy, heat energy and electrical energy. Energy can neither be created nor destroyed, but it can be transferred and changed from one form to another.
What is the formula to finding kinetic energy?
Using Kinetic Energy to Find Velocity or Mass Write the equation. The formula for calculating kinetic energy (KE) is KE = 0.5 x mv2. Plug in the known variables. In some problems, you may know the kinetic energy and the mass or kinetic energy and velocity. Rearrange the equation to solve for the unknown variable.
What are three examples of kinetic energy?
Because any moving thing or object has kinetic energy, there are many examples of this energy type, including a ball dropping into water, a car in motion and a moving arrow. However, there are different types or forms of kinetic energy. The three types of kinetic energy are vibrational motion, translational motion and rotational motion.
Is there a difference between kinetic and mechanical energy?
The difference between kinetic and mechanical energy is that kinetic is a type of energy, while mechanical is a form that energy takes. For instance, a bow that has been drawn and a bow that is launching an arrow are both examples of mechanical energy.
