What is velocity?
The relationship between gravitational force and mass
What is, gravitational force decreases as mass decreases?
(or force increases as mass increases)
The formula for calculating an object's weight
What is w=mg?
(w: weight, m: mass, g: gravitational force; answer should be in N)
This philosopher thought that objects with more mass would fall faster than those with less.
Who is, Aristotle?
The amount of matter in an object
What is mass?
The relationship between gravitational force and distance
What is, gravitational force decreases as distance increases?
(or force increases as distance decreases)
You will always have the same _____ throughout the universe.
What is mass?
This scientist experimented to prove that all objects fall at the same rate, regardless of mass.
(His full name is Galileo Galilei)
The resistance of matter to any change in its state of motion
What is inertia?
The way distance is measured when calculating gravitational force
What is, from the center of the objects?
The reason astronauts experience less gravitational force on the moon
What is, the moon has less mass than Earth?
The location where a famous scientist conducted his experiment, to prove that objects of different masses fall at the same rate
Where is, The Leaning Tower of Pisa?
(in Italy)
The attractive force between two objects due to their masses
What is gravitational force?
The average gravitational force between a human and the Earth
What is 588 N?
This celestial object has a mass 333,000 times more than that of Earth.
What is, the sun?
The reason a heavier object will fall at the same rate as a lighter one, is because of its ___________.
What is, inertia?
(Objects with more mass require more force to change their motion, so more applied force would be needed to overcome the gravitational force.)
The measurement of the force of gravity acting on an object
What is weight?
The unit of measurement for gravitational force
What is a Newton?
This planet's mass is only about 10% of Earth's mass.
What is, Mars?
The rate of gravitational acceleration for all objects with mass
(To figure out a falling object's change in velocity, multiply 9.8 by the number of seconds the object falls.)
