pressure and volume
|
|
|
velocity and mass
|
|
|
weight and height
|

|
temperature and weight

Explanation:
Detailed explanation-1: -Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed.
Detailed explanation-2: -It is obivious that doubling the velocity has a greater effect on the kinetic energy of a body than doubling its mass..
Detailed explanation-3: -Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
