A pure solid is heated at its melting point. While it is melting the
mean kinetic energy of the molecules of the solid increases.
mean potential energy of the molecules of the solid increases.
temperature of the solid increases.
temperature of the solid decreases.
What is the Equation for Weight?
Weight = Mass x Gravitational Field Strength
Weight = Mass / Gravitational Field Strength
Weight = Gravitational Field Strength / Mass
What is the Equation for Momentum?
Momentum = Mass x Velocity
Momentum = Mass / Velocity
Momentum = Velocity / Mass
What is the Equation for Kinetic Energy?
Kinetic Energy = 0.5 x Mass x Speed²
Kinetic Energy = 0.5 x Mass² x Speed
Kinetic Energy = 0.5 x Mass² / Speed
We receive ________ and heat energy from the Sun.
