What are mechanical devices that make work easier?
What are Simple Machines
Which Simple Machine reduces friction?
What is a Wheel and Axle
Which 2 simple machines can reduce the effort it takes to lift objects upwards?
What is an Incline Plane and a Pulley
Which simple machine is described as "an inclined plane wrapped around a cylinder"?
What is a screw
Before an object begins to move, the Total Mechanical Energy an object has is equal to its blank
What is Potential Energy
What do we call the ratio of output force to input force?
Mechanical Advantage
An object moves down a ramp without friction. The object loses potential energy and gains this type of energy.
What is Kinetic Energy.
DAILY DOUBLE EXTENSION PROBLEM!!!!!!!! The equation ∆PE = ∆KE shows how energy may be converted. In the same equation ∆mgh = ∆1/2*m*v^2, this property of the object cancels out in PE and KE.
What is mass. This means that the mass of the object does not matter when finding out how much energy is transferred from PE to KE or KE to PE.
