## How do you find kinetic energy at the highest point of a projectile?

When it reaches to the maximum height ,vertical component of its velocity becomes zero. Only horizontal component u cos ( theta) remains. u is initial velocity. If m is mass of the projectile, it’s kinetic energy at the maximum height will be K=(1/2)mu^2cos^2( theta).

### What is the formula for kinetic and potential energy?

At a start, the potential energy = mgh and kinetic energy = zero because its velocity is zero. Total energy of the object = mgh. As it falls, its potential energy will change into kinetic energy. If v is the velocity of the object at a given instant, the kinetic energy = 1/2mv2.

#### What is the kinetic energy at the maximum height?

zero/ maximum

At an object’s maximum height, kinetic energy is zero/ maximum while the potential energy is zero/ maximum.

**What is the formula for kinetic energy?**

Kinetic Energy Formula. Kinetic energy is the energy possessed by a body due to its motion. Kinetic Energy Formula is articulated as. Where, mass of the body = m, the velocity with which the body is travelling is v. The Kinetic energy is articulated in Kgm 2 /s 2.

**What is the potential and kinetic energy of a falling object?**

At a start, the potential energy = mgh and kinetic energy = zero because its velocity is zero. Total energy of the object = mgh. As it falls, its potential energy will change into kinetic energy. If v is the velocity of the object at a given instant, the kinetic energy = 1/2mv2.

## How do you calculate potential energy at 1m above the ground?

At 1 m above the ground it’s Potential Energy is. PE = m g h. PE = 0.1 kg × 9.8 m/s 2 × 1 m. PE = 0.98 kg m 2 /s 2. Ignoring air resistance (which is small for this little drop anyway) that PE gets converted into KE: KE = ½ m v 2. Swap sides and rearrange: ½ m v 2 = KE. v 2 = 2 × KE / m.

### What is the difference between kinetic energy and potential energy?

Potential Energy (PE) is stored energy due to position or state; PE due to gravity = m g h. Kinetic Energy (KE) is energy of motion; KE = ½ m v 2
