Why does a feather and a bowling ball fall at the same rate in an air vacuum?
they had the same mass
the pull of gravity was the same on both objects and there was air resistance
the pull of gravity was the same on both objects and there was no air resistance
they had the same weight
Newton's first law states that
an object will remain at rest unless an unbalanced force acts on it
an object will remain at rest unless a balanced force acts on it
Force = Mass x Acceleration
for every action there is an equal and opposite reaction
Newton's second law states that
an object will remain at rest unless an unbalanced force acts on it
an object will remain at rest unless a balanced force acts on it
Force = Mass x Acceleration (more mass needs more force or acceleration)
for every action there is an equal and opposite reaction
Newton's third law states that
an object will remain at rest unless an unbalanced force acts on it
an object will remain at rest unless a balanced force acts on it
Force = Mass x Acceleration
for every action there is an equal and opposite reaction
Newton's first law is also known as the law of
inertia
force
mass
balance
Potential energy is
happy energy
stored energy
energy of motion
force energy
Kinetic energy is

Maximus the doggo, who is a very good boi, was very excited to see a ball being tossed across a frozen, icy lake. He let out a "BORK!" and went running after it, but couldn't control where he went. Why did Max go slipping and sliding?
his nails are rough and have a good grip
he's a doggo, and everyone knows doggos slide
the bork gave him extra force
there isn't a lot of friction between his paws and the ice
A mechanical advantage, provided by simple machines like a ramp or a pulley, is when
something is easier to do due to the help of a machine or mechanical energy
Apple vs Android
something is harder to do due to the help of a machine or mechanical energy

Sir Isaac Newton
is responsible for the idea of heliocentristm
designed and built instruments to study the position of the planets
discovered planets move in an ellipse instead of a circle
wrote the laws of motion and developed ideas about gravity (a force or attraction between two masses)
Nicolaus Copernicus
is responsible for the idea of heliocentristm
designed and built instruments to study the position of the planets
discovered planets move in an ellipse instead of a circle
wrote the laws of motion and developed ideas about gravity
A theory is
a specific, testable prediction about what you expect to happen
backed up by evidence, not just an educated guess. It is highly reliable and well established by several researchers.
not necessary for an experiment
the thing the scientists changes
