1: Equilibrium
[] When two forces are equal in opposite directions, they are in a state of equilibrium
2: Friction
[] It can be hard to sometimes slide a paper across a table, roll a car across the ground, etc etc. This is because of a force called friction which resists motion
3: Displacement
[] Work is only "done" when the object or surroundings are having movement, or in motion, and this creates displacement
4: Force
[] A force is a push/pull in any direction, this is a simple definition so not much can be added.
5: Inertia
[] Inertia is a force that likes to remain unchanged, or without movement
6: Effort
[] "Meg is holding up weight without movement. She hasn't done any work since it did not move, but is tired. Why?" Effort! She still put in effort even though no "work" happened
7: Work
[] Force times displacement is the equation for work
8: Motion
[] Look back to #3, when there is motion we can tell work is done
Have a nice day!

Answer:
3.44:1
Explanation:
We use ratios to find the ratio of weight.
Mass of Plane= 110000 kg ∴ W= mg
Mass of Boat =31999 kg
=
=
SO 3.44:1
The efficiency of the device is 30 %
Explanation:
The efficiency of a heat engine is given by:

where
W is the work done by the engine
is the heat in input to the engine
For the device in this problem, we have:
W = 120 J is the work done
is the heat in input
Substituting, we find the efficiency:

which corresponds to an efficiency of 30%.

Answer:
A
Explanation:
Momentum conservation will cause 0.08kg to move to the west (opposite of 0.02 kg).
and because both are at the same height above the ground, they will take the same time to reach the ground.
The speed of 0.08kg will be less than 0.02 kg, let v be the speed of 0..02kg, then speed of 0.08kg V is
0.02v - (0.08)V = 0
V = 0.02 v/ 0.08 = v/4
The speed of 0.08 kg = v/4
The speed of 0.08 kg is less than 0.02kg.
So 0.02kg strikes the ground farther from the launch point than does the 0.08 kg
