Potential energy
Formula to calculate Speed??
V=S/t
What is "g"?
Acceleration due to gravity in formulas
The unit for work and energy
What is the Joule
What is neutons first law?
The velocity of a body remains constant unless the body is acted upon by an external force
unit of acceleration
m/s^2
the normal range for human hearing
20-20 000Hz
Who introduced the concept of absolute zero?
Lord Kelvin
The difference between weight and mass
What is Weight is how gravity acts on an object, mass is what makes up the object.
true or False: Absolute zero is the lowest limit of the thermodynamic temperature scale
True
What is 10 Degrees Celsius in Fahrenheit?
50 Degrees Fahrenheit
What is neutons second law?
F=ma. The acceleration a of a body is parallel and directly proportional to the net force F and inversely proportional to the mass m, i.e.,
Who created the Celsius temperature scale?
Anders Celsius
the attractive force that acts on all objects everywhere
gravity
Boltzmann’s constant=?
K=1,38*10^-23 J/K
Newtons 3rd law
What is when a force is exerted an equal force is acting in the opposite direction
Difference between speed & velocity
Velocity is has a vector/direction
He is often referred to as one of the "Founding Fathers" of modern physics.
Isaac Newton
The force of gravity on the object; may be defined as the mass times the acceleration due to gravity
weight
