Conservation of Rotational Kinetic Energy
Internal energy is made up of kinetic energy and the potential energy of the constituent particles. The answers given here for the speed values are presuming that all the kinetic energy of the ball is in the form of translational kinetic energy.

Get rotational motion formulas list by following this link.
. Physics 03-06 Impulse and Momentumpdf. Motion of wheel gears motors etc is rotational motion. E ½mv 2 where m is mass and v is velocity so the equivalent kinetic energy of a spinning object is given by this one.
NUMERICALS BASED ON WORK ENERGY AND POWER. Energy is always conserved. Conservation of Mechanical Energy.
Work done by variable force. In Newtonian mechanics linear momentum translational momentum or simply momentum is the product of the mass and velocity of an object. If m is an objects mass and v is its velocity also a vector quantity then the objects momentum p is.
A body when acted upon by a force of 10kgf gets displaced by 05m. Understanding kinetic energy is intuitively easier because its more obvious that moving things have energy. Naturally the kinetic energy of an object at rest should be zero.
Using the equation KE 05mv 2 the velocity can be determined to be 707 ms for B and E and 10 ms for H and K. Mass on a Vertical Spring. Inclined Plane with Friction Two Masses and a Pulley.
E ½Iω 2 where I is the moment of inertia and ω is the angular velocity. We see rotational motion examples in our daily life. The potential energy arises from different types of interaction between the particles and it includes electronic.
Physics 03-02 Potential Energy and Conservative Forcespdf. Some of the examples of rotational motion are Rotation of earth about its own axis create the cycle of day and night. Thus an objects kinetic energy is defined mathematically by the following equation.
Kinetic energy is determined by the movement of an object or the composite motion of the components of an object and potential energy reflects the potential of an object to have motion and generally is a function of the. It is a vector quantity possessing a magnitude and a direction. In some situations rotational kinetic energy matters.
Work Energy and Power This chapter is about Work done by a force Kinetic energyPotential energy Conservative forces Law of Conservation of energyPower Elastic Inelastic Collisions Notes Work Energy and Power. Concepts of work kinetic energy and potential energy are discussed. Kinetic energy is the energy of motion.
Just as the kinetic energy of an object moving in a straight line is given by this equation. The kinetic energy arises due to the motion of its particles like translational energy rotational energy vibrational energy etc. When it does it is one of the forms of energy that must be accounted for.
Kinetic energy is created when potential energy is released spurred into motion by gravity or elastic forces among other catalysts. Elliptical Orbits. Physics 03-05 Energy in Humans and the Worldpdf.
Elastic and Inelastic Collisions. When work is done on an object and it accelerates it. Static and Kinetic Friction on an Inclined Plane.
Physics 03-01 Work and the Work-Energy Theorempdf. These concepts are combined with the work-energy theorem to provide a convenient means of analyzing an object or system of objects moving between an initial and final state. K ½mv 2.
Physics 03-03 Nonconservative Forces and Conservation of Energypdf. Thomas Young 17731829 derived a similar formula in 1807 although he neglected to add the ½ to the front and he didnt use the words mass and weight with the same precision we do nowadays. And so the kinetic energy at the bottom of the hill is 100 J G and J.
Calculate the work done by the force when the displacement is i in the direction of force ii at an angle of 600 with the force iii normal to the forceg 10 N kg-1. The total energy of a system can be subdivided and classified into potential energy kinetic energy or combinations of the two in various ways. In the International System of Units SI the unit of measurement of.
F 10kgf 10 10N 100 N S 05m i Work done when.
