Question

How would you describe the relationship between the mass of a car and its kinetic energy?

A) As the mass of a car increases, its kinetic energy increases.
B) As the mass of a car increases, its kinetic energy decreases.
C) As the mass of a car decreases, its kinetic energy increases.
D) There is no clear relationship between mass and kinetic energy.

Answer 1

A) they both increase

Answer 2

The answer is A) As the mass of a car increases, its kinetic energy increases.

Step-by-step explanation:

Kinetic energy is the energy associated with bodies that are in motion, depends on the mass and speed of the body, that is, The kinetic energy of a body depends on its mass and its speed according to the relationship.

The kitenic energy is expressed by the formula:

`Ec=(1)/(2) mv^(2)`

Where the kinetic energy, (Ec) is measured in joules (J), the mass, (m) is measured in kilograms (kg) and the velocity, (v) in meters / second (m / s).
