What is the formula for mass
Mass=Density/Volume
A PUSH OR A PULL
Force
WHAT HAPPENS TO PARTICLES WHEN THEY ARE HEATED
THEY MOVE FASTER AND SPREAD FURTHER
What is force measured in?
Newtons
The ability to do work
Energy
Can energy be created or destroyed?
Energy can only be transformed
Name 3 types of energy
Thermal, light, sound, mechanical, electrical; kinetic and potential
if an object has two forces acting upon with at opposite directions with the same amount of force, what is it called?
A balanced force
force formula
F = MxA
If you push a cart towards somebody with 35 newtons of force and they push a cart in the same direction with 40 newtons of force, which cart will end up getting to the opposing end and how much force will it have?
What Is: the second cart, 5 newtons
what is newtons second law?
the acceleration of an object depends upon two variables which is the net force acting on the object and the mass of the object.
Which object will have more of a gravitational pull: the Sun, the Earth, or a pencil?
the Sun
If there are two forces acting upon an object, one pushing 160 newtons to the left, one pushing 190 newtons to the right, what direction would it move at how many newtons?
right 30 newtons
Density formula
D = mass/volume
A battery is used to power a heater which can also work by charging it. What types of energy are in this situation?
Chemical, Electrical, Thermal
What is newtons first law?
every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
What type of energy is contained in the food you eat?
Chemical
What are the four types of energy used in a campfire?
Thermal (heat from fire), Light (light emitted from fire), Sound (fire crackling), Chemical (wood burning).
ENERGY MEASURED IN UNITS
JOULES/WATTS
What energies come from the sun from the sun and what energies can it be converted to?
Solar, Light, Thermal, and it can be converted into electrical.
Volume Formula
volume=mass/density
The point after the drop has the most kinetic energy.
John is taking a walk outside in the sun without any rests, he eats a burger and checks the time on his smart watch that has batteries in it. What kinds of energy are exerted on John and used by John?
(there are 6 energy type used.)
Kinetic Energy, Chemical energy, Mechanical energy, Electrical Energy, Thermal energy, Light energy.
Acceleration formula
a= ∆v/∆t (change in v divided by change in t)
What energies does the human body use while eating
Chemical, Kinetic, Potential, Mechanical.
