Question

Which object has the least amount of kinetic energy? a car driving down a road a soccer ball rolling down a hill a bicycle locked to a bike rack a satellite orbiting Earth

Answer 1

a bicycle locked to a bike rack im pretty sure

Answer 2

Answer:

A bicycle locked to a bike

Explanation:

The kinetic energy of an object when an object is moving. The mathematical expression for the kinetic energy of an object is given by :

$KE=\dfrac{1}{2}mv^2$

Where

m is the mass of an object

v is the velocity of an object

First option : A car driving down a road, the car is moving i.e. it will possess kinetic energy.

Second option : A soccer ball rolling down a hill, the ball is moving i.e. it will possess kinetic energy

Third option : A bicycle locked to a bike, neither bicycle nor bike is moving i.e. it will not possess kinetic energy.

Fourth option : A satellite orbiting Earth, the satellite is moving i.e. it will possess kinetic energy.

Hence, "a bicycle locked to a bike " has least amount of kinetic energy.
