Energy equals mass times the speed of light squared; it shows the equivalence of energy and mass.
Energy equals mass times velocity squared; it shows the conservation of energy.
Energy equals work done per unit time; it shows the rate of power consumption.
Energy equals force times distance; it shows the relationship between work and energy.
Gravity is not a force but a curvature in spacetime caused by mass.
Gravity is a force that attracts all objects towards the center of the Earth.
Gravity is the result of magnetic attraction between masses.
Gravity is a constant force exerted by all objects in the universe.
A four-dimensional continuum that combines the three dimensions of space with the dimension of time.
A theoretical concept that suggests time can be reversed under certain conditions.
An alternative theory that proposes time is a separate entity from space.
A fixed boundary that limits the extent of the universe.
Mass curves spacetime, causing objects to follow curved paths.
Mass has no effect on spacetime; it only affects gravitational pull.
Mass accelerates time, altering the passage of time for nearby objects.
Mass alters the speed of light through different areas of space.
