When a ball is thrown upwards, its total energy (neglecting air friction) remains same. Give reason.

Conservation of Energy. Energy is conserved in nature. Energy can not be created or destroyed.
we can convert the energy from one form to other.
In the case of ball thrown vertically, potential energy(PE) keep on increasing and kinetic energy(KE)
keep on decreasing and the total of PE and KE remains same.

- a bus of mass 10000kg with a velocity of 90 km/h. calculate work done to stop the bus
- define kinetic energy
- what is kinetic energy
- Hi, my name is Aprameya i had a doubt we know K.E.(Kinetic Energy) = (1/2)mv^2 the v over here is velocity but at what time. Velocity will be different at differnt points of time i mean at 1second it might be something and and at another second it might be something else. so while calculating which velocity do we use
- what is energy
- A ball of mass 0.25kg is thrown upwards with a velocity of 10m/s at what height it's kinetic energy become 10J
- The water stored in dam can be used to generate electricity.give reason
- What is work ?
- A truck of mass 5000kg travelling at 40m/s is brought to rest by applying breaks the truck comes to rest after travelling 20m after the application of break what is the kinetic energy of truck
