Machines
100
Energy an object possess due to activation energy.
What is kinetic energy?
100
The tendency of an object to resist changes in its velocity: whether in motion or motionless.
What is inertia?
100
The amount of matter of an object that measures its resistance and acceleration, usually measured in grams.
What is mass?
100
Mass x Acceleration
What is force?
100
A machine can make this easier, but it can not do it for you.
What is work?
200
Energy that is stored to be used by activation.
What is potential energy?
200
The force that opposes motion between a car's wheels and the surface of a road.
What is friction?
200
The force of gravity applied to an object's mass at the surface of a planet.
What is weight?
200
Work done over a period of time.
What is power?
200
The amount of output should be greater than the amount of input effort.
What is mechanical advantage?
300
The potential energy stored in an alkaline battery.
What is an example of chemical potential energy?
300
The more force an object receives, the greater its acceleration.
What is Newton's 2nd Law?
300
Two factors that affect the gravitational attraction between two objects.
What is mass and distance? *Greater the mass = Increase the gravitational attraction. Greater the distance = Decrease the gravitational attraction.
300
A motor does 5,000 joules of work in 20 seconds. Name the calculation and solve the problem.
What is power/ 250 watts
300
A rigid bar or plank that rests on a support called a fulcrum.
What is a lever?
400
A cinder block is sitting on a platform 20 meters high and is weighs 79 N. Name the energy, calculation, and solve the problem.
What is potential energy, PE = Weight x Height, 1580 Joules.
400
When a hammer strikes a nail an equal or opposing force of energy is created.
What is Newton's 3rd Law?
400
All objects falling through air experience a type of fluid friction.
What is air resistance?
400
Force x Distance
What is work?
400
Knowing the length and the height would help in the calculation of this simple machine.
What is an incline plain?
500
A 3 kilogram ball is rolling down a hill at 2 meters per second. Name the energy, calculation, and solve the problem.
What is kinetic energy, KE = .05 x mass x velocity squared, 6 Joules
500
Because of inertia, objects (including you) resist changes in their motion. When a car is going 80 mph and is suddenly stopped by hitting another car, your body keeps moving at 80 mph.
What is Newton's 1st Law?
500
Does not change its measurement regardless of gravitational attraction.
What is mass?
500
The amount of watts created by an object, person, animal, or object.
What is power?
500
A wheel on an axle attached to a rope or cable that can change the directional force to move an object up or down.
