Force
The SI unit of force.
What is a / are Newton(s)?
Work has magnitude, but no direction. We call this a ___________.
What is a scalar?
The SI unit of energy.
What is the / are Joule(s)?
The SI unit of temperature.
What is Kelvin?
Weight is nothing more than this.
Force is proportional to mass and this other quantity.
What is acceleration?
Work is proportional to displacement and this other quantity.
What is force?
A body gains more of this type of energy when its speed increases.
What is kinetic (energy)?
We call the minimum temperature any body in the universe can reach this.
What is absolute zero?
Velocity, acceleration, and displacement are all this.
What is a / are vector(s)?
Mass is always conserved, but this can change depending on the planet.
What is weight?
Work can also be defined as this.
What is change in kinetic energy?
A body gains more of this type of energy when its height above the Earth's surface increases.
What is potential (energy)?
The temperature of a body or system is defined as the _________________.
What is the average kinetic energy of all the particles (in the system/body)?
Power is the rate of change of this over time.
What is work?
An object whose form and shape is permanently altered is said to be in this state.
What is inelastic deformation?
Work can be negative. This happens when the kinetic energy of a body does this.
What is decrease(s)/decreasing?
The PE + KE of a body will always _________.
What is "be conserved" / "remain the same"?
Thermal energy can arise from many interactions between bodies and surfaces. This is the most common source of thermal energy.
What is friction?
You ride your bike and create 1000 J of kinetic energy when pedalling. Your kinetic energy isn't created though, it's just transformed from this other form of energy.
What is chemical (energy)?
Hooke's law states that the restoring force is proportional to the negative displacement. This is because restoring force and displacement have this property with opposite signs.
What is direction?
What is area?
You have multiple pulleys helping you pull a heavy box. It requires less force than with one pulley. The ______ force which you put in, the ______ displacement you get out.
What is "less", "more" / "more", "less"?
A body of 400 K is put into a container with a body of 100 K. They will eventually exchange energy and reach this state.
What is thermal equilibrium?
PE = mgh is this specific kind of potential energy.
What is gravitational?
