Rubber bands can be classified as both potential and kinetic energy, depending on the state of the band. … 3) Rivers. … 4) Specific Variations.

What is watt Class 9?

Watt, denoted by W, is a unit of power. In the International System of Units (SI) it is defined as an amount of 1 Joule energy used per sec, and is used to quantify the rate of energy transfer with respect to time. In SI base units, the watt is described as kg m2 s-3.

What is the formula for potential energy?

The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

What is potential and kinetic energy?

Kinetic and Potential Energy: Energy stored in an object due to its position is Potential Energy. · Energy that a moving object has due to its motion is Kinetic Energy.

What is total energy formula?

EquationsEquationMeaning in wordsE m = K + U E_\text m = K +U Em=K+UThe total mechanical energy of a system is the sum of the total kinetic energy and total potential energy.2 more rows

What are 2 examples of potential energy?

Examples of Gravitational Potential EnergyA raised weight.Water that is behind a dam.A car that is parked at the top of a hill.A yoyo before it is released.River water at the top of a waterfall.A book on a table before it falls.A child at the top of a slide.Ripe fruit before it falls.

What is SI unit of potential energy?

Potential energy is energy stored in matter. The joule (J) is the SI unit of energy and equals (kg×m2s2) ( kg × m 2 s 2 ) .

What is the formula of work done?

What is Work, Energy and Power?WorkDefinitionWork is said to be done when a force applied to an object moves that object.FormulaWe can calculate work by multiplying the force by the movement of the object. W = F × dUnitThe SI unit of work is the joule (J)8 more rows

What are 5 types of potential energy?

Presenting, 5 Types of Potential Energy. Potential energy is stored energy that can be converted into kinetic energy. There are several forms of potential energy including gravitational, magnetic, electrical, chemical, and elastic potential energy.

What is the formula of potential energy Class 9?

Here, the mass of the object (m) = 1 kg, Displacement (height) (h) = 10 m, Acceleration due to gravity (g) = 9.8 m s–2. Hence, Potential energy (p) = m×g×h = 1 kg × 9.8 m s–2 × 10 m = 98 J.

What is potential energy class 10?

Hint: We know that potential energy is equivalent to the work done against the gravitational force. … Potential energy is the energy possessed by a body because of its position relative to other bodies.

What is potential energy in simple words?

To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.

What is the best example of potential energy?

To better explain this phenomenon, we have gathered some interesting examples of potential energy that you see in your everyday life.A Pendulum. Type: Gravitational Potential Energy. … Rock At The Edge Of A Cliff. … Water Behind Dams. … Tree Branches. … Roller Coaster. … Spring. … Bow and Arrow. … Stretched Rubber Bands.More items…•Mar 21, 2020

What is work done class 9?

Work done on an object is defined as the product of the magnitude of the force acting on the body and the displacement in the direction of the force. W = F.s. If a force acting on a body causes no displacement, the work done is 0. For example, pushing a wall.
