Questions with Verified Answers
A force that pulls objects toward each other - CORRECT ANSWER Gravity
the greater the force of gravity it exerts. - CORRECT ANSWER The more mass an
object has
an attractive force that acts between any two objects - CORRECT ANSWER
gravitational force
weaker than the gravational force you feel when you stand on Earth. - CORRECT
ANSWER Earth's Mass is much greater than that of the moon. IF you were to stand
on the surface of the moon, the gravitational force you would experience from the
moon would be
gravity. - CORRECT ANSWER The force that keeps a planet in an orbit around the
sun is called
both gravity and static friction. - CORRECT ANSWER If two books are place one on
top of the other, the books are experiencing
Both pieces of cardboard will experience the same gravitational force. - CORRECT
ANSWER A scientist drops two pieces of cardboard from the top of a building to
observe how they fall. One piece of cardboard is in a flat sheet, and the other is
,folded into a small cube. The two pieces of cardboard have exactly the same mass.
Which piece of cardboard experiences the greater gravitational force?
the flat one encounters more air resistance, which slows it down. - CORRECT
ANSWER If a crumpled-up piece of paper and a flat piece of paper are dropped
from the same height at the same time, the crumpled-up one will fall faster to the
ground. They fall at different speeds because
the force of gravity between any two objects is directly proportional to their
masses and inversely proportational to the square of the distance between them.
- CORRECT ANSWER Newton's law of universal gravitation
both the objets' masses and the distance between them - CORRECT ANSWER
What affects the gravitational force between two objects?
a smaller force of gravity than it pulls a truck. - CORRECT ANSWER Earth pulls a
bike with
is decreased - CORRECT ANSWER If the distance between two objects is doubled,
the force of gravity between them
the same as the force of gravity exerted by you on the Earth. - CORRECT ANSWER
The force of gravity exerted by the Earth on you is
is the mass of an object times its velocity. - CORRECT ANSWER linear momentum
, The train has more momentum. - CORRECT ANSWER A bicycle and train are
moving at exactly the same velocity. Which has more momentum, the bicycle or
the train?
The train moving at 100 km/hr has more momentum. - CORRECT ANSWER Two
identical trains are traveling on parallel tracks. One is moving at 10 km/hr and the
other is moving at 100 km/hr. Which train has more momentum?
a scientific law that states that momentum is conserved when two or more
objects collide. (or momentum can be transferred) - CORRECT ANSWER law of
conservation of momentum
Due to frictin, the ball gradually loses kinetic energy. - CORRECT ANSWER A ball
rolling across a smooth floor gradually slows to a stop. Why?
The total momentum of both balls must be the same before and after the
collision. - CORRECT ANSWER One pool ball collides with another, and the balls
move away from one another. Which of the following statements is true (assume
there are no losses to heat or friction)?
Physics - CORRECT ANSWER A mathematical model is used to predict the
trajectory of a bullet fired from a gun. Which discipline of physical science is used
to develop this model?
Chemistry and Earth science - CORRECT ANSWER An environmental scientist
monitors pollutants in a lake. Which two disciplines of physical science does this
scientist use?
