Newton's First Law/Thermal Energy

Front

What is Newton's First Law of Motion?

Back

Newton's First Law states that an object at rest will remain at rest, and an object in motion will continue in motion at a constant speed and in a straight line unless acted upon by an unbalanced force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It depends on the mass of the object.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia. This means heavier objects are harder to start or stop moving.

Front

What happens to a resting object according to Newton's First Law?

Back

A resting object will remain at rest unless acted upon by an unbalanced force.

Front

What happens to a moving object according to Newton's First Law?

Back

A moving object will continue to move at a constant speed in a straight line unless acted upon by an unbalanced force.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance, which is related to its temperature.

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.

Front

What are the three methods of heat transfer?

Back

The three methods of heat transfer are conduction, convection, and radiation.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.
