Newton's 1st Law and Thermal Energy

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What causes a baseball player to stop when sliding into second base?

Back

Friction between the player and the ground.

Front

What happens to an object when the forces acting on it are balanced?

Back

The object will not move or change its motion.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.

Front

How is thermal energy transferred through radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, such as sunlight.

Front

What is convection?

Back

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

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

Which object has the least amount of inertia: a ladybug, a truck, a textbook, or Mr. Nye?

Back

A ladybug has the least amount of inertia.

Front

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward each other, affecting their motion and acceleration.
