Energy and Mass Concepts in Physics

Front

What happens to kinetic energy when velocity triples?

Back

Kinetic energy increases by 9 times.

Front

What is the rest-mass energy of one gram of any substance?

Back

9 x 10^13 J.

Front

At which point on a roller coaster is gravitational potential energy at its maximum?

Back

Point A.

Front

What is the term for the difference between the mass of an atom and the sum of the masses of its parts?

Back

Mass-defect.

Front

What is the formula for calculating gravitational potential energy?

Back

Potential Energy (PE) = mass (m) × gravitational acceleration (g) × height (h).

Front

How is kinetic energy calculated?

Back

Kinetic Energy (KE) = 1/2 × mass (m) × velocity (v)^2.

Front

What is the unit of energy in the International System of Units (SI)?

Back

Joule (J).

Front

What is the relationship between mass and energy according to Einstein's equation?

Back

E = mc^2, where E is energy, m is mass, and c is the speed of light.

Front

What is gravitational potential energy dependent on?

Back

Mass, height, and gravitational acceleration.

Front

What happens to potential energy as an object falls?

Back

Potential energy decreases while kinetic energy increases.
