This type of motion occurs when all parts of an object move the same distance, in the same direction, at the same time.
What is translational motion?
This simple machine is a rigid beam that pivots around a fixed point called a fulcrum.
What is a lever?
When ironing clothes, this type of energy transfer passes heat from the iron to the fabric.
What is heat transfer?
This resistance force is created when two contacting machine parts slide against each other.
What is friction?
This type of motion occurs when an object spins or rotates about an axis.
What is rotational motion?
This simple machine is also called a ramp and has no moving parts.
What is an inclined plane?
This physics concept explains why seatbelts protect passengers by managing the change in momentum over time.
What is impulse (and momentum)?
This force is caused by gravity pulling objects downward and depends on mass and gravitational field.
What is weight?
This linear quantity is the change in position of an object, measured in meters.
What is linear displacement?
This simple machine is an inclined plane wrapped around a cylinder, often used to hold objects together.
What is a screw?
Levers, pulleys, and gears are examples of machines that improve this workplace quality by reducing effort and saving time.
What is efficiency (or productivity)?
This force is transmitted through ropes, cables, or strings and acts along the length of the material.
What is tension?
This angular quantity is the rate of change of angular displacement, measured in rad/s.
What is angular velocity?
In this class of lever, the fulcrum sits between the load and the effort, as in a pair of scissors.
What is a first class lever?
On a roller coaster, this form of energy is highest at the top of a hill and converts into kinetic energy as it descends.
What is potential energy?
This force causes rotation and is measured in newton-meters (N·m)
What is torque?
A rolling wheel, a rolling ball and moving vehicle tires are all examples of this combined type of motion.
What are examples of translational and rotational motion combined?
This type of pulley is attached to a fixed point, like a flagpole, and only changes the direction of the force — not the amount of effort needed.
What is a fixed pulley?
Physics supports this branch of science by explaining blood flow, muscle movement, vision, and hearing.
What is biology?
Pushing a heavy crate across the floor requires overcoming this resistance force, which can either help or hinder a machine's operation.
What is friction?
