Q. What is the kinetic energy of an object?
KINETIC ENERGY
In chemistry, kinetic energy is defined as the amount of work an object accomplishes as a result of its motion. Everyday activities such as walking, climbing, tossing, and dropping consume kinetic energy.
Energy is defined as the ability to do labor or produce heat.
To accelerate an item, we must apply force, and we must labor to apply force. When work is done on an object, energy is transferred, and the object moves at a new constant speed. Kinetic energy is the amount of energy transferred and is dependent by the mass and speed reached.
HOW DOES KINETIC ENERGY GET CALCULATED?
Kinetic energy is a scalar quantity that can only be expressed in magnitude terms. The kinetic energy is measured in Joules (J).
The kinetic energy equation is given as follows;
k = 12mv2
Where K is the kinetic energy, m is the body’s mass, and v is the body’s velocity.
EXAMPLES OF KINETIC ENERGY
- A truck travelling down the road has far more kinetic energy than a car travelling at the same speed due to its mass.
- A river moving at a set speed includes kinetic energy because water has a specific velocity and mass.
- An asteroid colliding with Earth has a lot of kinetic energy.
- Due to its enormous mass and fast velocity, the aeroplane’s kinetic energy is higher during flight.
