What is the formula for Newton’s 2nd law of motion?
F = ma
E = mc^2
V = IR
P = IV
What is the formula for speed?
Speed = Distance / Time
Speed = Time / Distance
Speed = Distance x Time
Speed = Distance + Time
Which is needed to determine the amount of gravitational force between two objects?
weight and time
distance and mass
volume and mass
area and weight
What is the relationship between mass and gravitational pull?
Lower gravitational pull creates more mass.
Higher gravitational pull creates more mass.
Lower mass creates higher gravitational pull.
Higher mass creates higher gravitational pull.
The gravitational force exerted by an object depends on its
volume.
weight.
mass.
size.
Complete this sentence by choosing the correct second part of the sentence: As distance increases between objects...
gravitational force increases
gravitational force stays the same
gravitational force decreases
the size of the object increases
Planets X and Y orbit each other in space. Which changes would have the greatest effect on increasing the gravitational attraction between the two planets?
doubling the mass of planet X and halving the distance between the planets
halving the mass of planet X and doubling the distance between the planets
Which pair of objects will have the greatest force of gravity between them?
objects that are small and far apart
objects that are small and close together
objects that are large and far apart
objects that are large and close together
When placed at equal distances apart, the greatest gravitational attraction will be between two
skateboards.
refrigerators.
bowling balls.
school buses.
How do we know our weight would be different on other planets?
Our mass would stay the same on whatever planet we are on.
Our weight is a measure of the pull of gravity on an individual object, which would vary on objects' of different masses.
The greater the mass of an object, the greater the gravitational force and planets have different mass and different gravitational force.
All of the above are correct.
The gravitational force on an object on the surface of the Moon is 1/6 that of the gravitational force on the same object on the surface of Earth. Why is the gravity acting on the object on the Moon less than the gravity acting on the object on Earth?
because the distance from Earth to the object has increased
because the mass of the Moon is less than the mass of Earth
because Earth is rotating at a faster rate than the Moon is rotating
because the pull on the object from Earth counteracts the pull from the Moon
