Motion - Bill Nye

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.

Front

Which object requires the least force to move: a golf ball, baseball, basketball, or soccer ball?

Back

A golf ball (1.62 oz) requires the least amount of force to move because it has the least mass.

Front

What is condensation?

Back

Condensation is the process by which water vapor in the air cools and changes into liquid water, often seen as droplets on a surface.

Front

What type of energy is carried by electromagnetic radiation?

Back

Radiant energy is the type of energy carried by electromagnetic radiation, such as light from the sun.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it comes into contact with another surface.

Front

What is momentum?

Back

Momentum is the quantity of motion an object has, which depends on its mass and velocity. It is calculated as momentum = mass x velocity.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can be a change in speed or direction.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object, related to its position and 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.
