Weight is caused by the influence of gravity on matter/mass. Weight is given by the formulae;
Weight = Mass * Gravitational acceleration
On earth, the gravitation acceleration is a constant 10m/s2
Therefore the weight will be influenced by mass of the object in a direct relationship.
An increase in mass will cause a proportionate increase in weight.
Explanation:
Gravity is not constant across the universe with larger celestial bodies have a greater gravitational pull. Therefore an object with the same mass on earth may weigh differently on another celestial body with different gravitational acceleration. An example is the Moon. Due to the fact that the Moon has approximately ¹/3 of earth’s gravitational force, astronauts weight ¹/3 times less on the moon than on earth.

Answer:
Lilly's speed is two times John's speed.
Explanation:
m = Mass
a = Acceleration
t = Time taken
u = Initial velocity
v = Final velocity
The force they apply on each other will be equal
Hence, Lilly's speed is two times John's speed.
Its like a shoter way or writing "to the power" I think.
