Physics of Toys Vocabulary

Bernoulli's Principle: For a fluid undergoing steady flow, the pressure is lower where the fluid is flowing faster (Day 10)

Energy: The measure of a system's capacity to do work. (Day 2)

Force: A push or pull acting on a body. (Day 1)

Friction: The resistance that results when two surfaces rub against each other. (Day 3, 4, 5)

Gravity: The force of attraction existing between two bodies. (Day 1)

Inertia: A resistance to a change in motion (Day 4, 5)

Kinetic energy: The energy an object has because it is moving or energy due to motion. (Day 2, 7, 8)

Longitudinal Wave: A wave in which the vibration is in the same direction as that in which the wave is traveling, rather than at right angles to it. Sound waves are longitudinal waves. (Day 5)

Momentum: An object's mass times its velocity. The heavier an object, or the faster it is going, the more momentum it has. (Day 7)

Newton's First Law of Motion: An object at rest or in motion will remain that way unless acted on by an external force. (Day 4)

Newton's Second Law: A force on an object will cause it to accelerate in the direction of the force. The greater the mass of an object, the harder it is to change its speed. This is the law of acceleration. (Day 9)

Newton's Third Law: For every action, there is an equal and opposite reaction. This is the law of interaction. (Day 9)

Potential energy: Energy due to an object's position or orientation that can do work at some future time. (Day 2, 8)

Rotational Inertia: The resistance of an object to change its rotational state of motion (Day 6)

Transverse Wave: A wave in which the vibration is at right angles to the direction in which the wave is traveling. Waves in the stretched strings of musical instruments, upon the surfaces of liquids, and the electromagnetic waves, which make up radio waves and light are transverse. (Day 5)

Variable: A change made in an experiment (Day 6)

Velocity: The speed and direction with which an object is moving (Day 7)

Weight: The measure of how strong the force of gravity is between an object and the Earth. (Day 1)
