Work is done when which two things happen?
an object is moved
power is converted into Newtons
an object has been subjected to force (unbalanced)
an object stays in place
A simple machine is (a)
Due to (a) , the work put into a machine is always greater than the work output
The ratio of work output to work input is called (a)
Work is measure in (a)
Power is measure in
Newtons
Joules
Joules per Second (J/s)
Watts
The greater the mass of an object being moved, the greater amount of force needed to move (accelerate) the object.
Law of Inertia
Law of Force Pairs
Law of Acceleration
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force (a)
For every action there is an equal and opposite reaction. This is the (a)
A rocket pushes burning gases DOWN which causes the rocket to launch UP. Which law is this?
Newton's 1st Law - Law of Inertia
Newton's 2nd Law - Law of Acceleration
Newton's 3rd Law - Law of Force Pairs (Action, Reaction)
(a) do not cause an object to move.
If force is applied to an object on two sides, and that force is NOT the same, then the object will move in the direction of the greater force. Which type of force is responsible for this?
Balanced Force
Unbalanced Force
Energy due to motion is (a) energy.
(a) is stored energy.
At which point is the energy greatest?
Greatest Potential
Greatest Kinetic
Visible light is a form of (a) energy
Sound is a form of (a) energy
(a) is a measure of the average kinetic energy of the molecules of a substance

Conduction
Convection
Radiation
An (a) is a reflected sound.
(a) is the amount of energy in a sound wave.
Sound is a form of energy produced by (a) .

Amplitude
An object through which electrons and heat do NOT easily flow is called a(n) ; (a) ; these tend to be (b) .
An object which can act as a one-way valve or a switch to turn a cicurit on/off is called a(n) (a) ; these tend to be (b) .

wedge
inclined plane
Wheel and axle
screw
lever (with a wedge on the end)
Honey badgers are something even lions are terrified of, because with their 0.083 m mouth, in 0.75 seconds they can bite with an astonishing 220 Newtons of force (or more depending on which website you look on). For reference, a human skull can break at 14 Joules.
Work: (a)
