When two objects collide or bump into each other, causing an exchange or transformation of energy.
A limitation or a restriction such as time, materials, or size.
Guidelines or rules used to judge or make a decision about something.
A step by step way to solve problems that is used to develop many possible solutions to a problem and then narrow down the possible solutions to one final choice.
A collision with no loss of kinetic energy.
The ability to do work.
A person who is trained to use technology and science to solve problems.
The use of technology and science to solve problems.
A push or pull that can make an object move, stop moving, or change directions.
A simple machine that is a sloping (or slanted) ramp that can be used to raise or lower a load by sliding. The slanted ramp helps to move things between lower and higher levels.
A collision in which part of the kinetic energy is changed into another form of energy. Inelastic collisions may result in objects "sticking together," such as when a large truck collides with a small car and pushes it over a distance.
Energy that an object has because of its motion.
A simple machine that moves a load around a fulcrum using a force.
Energy that is stored; energy that matter has because of its position.
A working model than can be tested and evaluated.
A simple machine that uses grooved wheels and a rope to raise or lower a load.
A simple device that makes work easier by helping to move an object over a distance. Simple machines include levers, inclined planes, pulleys, wheels and axles, wedges, and screws.
The rate at which an object moves or operates. Speed can be thought of as the amount of time it takes to complete a task.
A result of force moving an object a certain distance.
