Q

How do you graph uniform motion?

A

The slope of a distance-time graph is a visual representation of the speed of an object.
The greater or steeper the slope indicates a faster speed

16
Q

What is the formula for force?

A

F = m*a

Force = mass*acceleration

17
Q

Work

A

Work is done when force moves an object through a distance

Is scalar

18
Q

What are the conditions for work to take place?

A
  1. There must be movement
  2. There must be force applied
  3. Force and distance moved must be in the same direction
19
Q

What is the formula for work?

A

W = F*d

Work = force*distance

20
Q

Potential Energy

A

Is stored energy
Has the potential to make change occur
Useless unless converted to another form

21
Q

What is the formula for potential energy?

A

E = mgh

E = massgravity(9.81)height

22
Q

Gravitational Potential Energy

A

Energy of an object due to its position above the surface of the earth

23
Q

Kinetic Energy

A

Is the energy due to the motion of an object

24
Q

What is the formula for kinetic energy?

A

E = 1/2m*v^2

E = 1/2mass*speed^2

25
Q

Mechanical Energy

A

Is the energy associated with the motion and position of the object

26
Q

What is the formula for mechanical energy?

A

Mechanical Energy = Kinetic Energy + Potential Energy

27
Q

What are the three types of systems?

A

Open systems
Closed systems
Isolated systems

28
Q

What is an open system?

A

Exchanges both matter and energy with its surroundings

29
Q

What is a closed system?

A

Cannot exchange matter but can exchange energy with its surroundings

30
Q

What is an isolated system?

A

Cannot exchange matter or energy with its surroundings

31
Q

What is the formula for the energy in a system?

A

Energy in a system = heat + work

32
Q

What are the two laws of thermodynamics?

A

States that the total energy, including heat, in a system and its surroundings remains constant

States that heat always flows naturally from a hot object to a cold object, but never from a cold object to a hot object

33
Q

What is the formula to calculate the percentage of efficiency?

A

Percent efficiency = (output/input)*100
