100
This is the force of gravity on any object.
What is weight?
100
This is a basic unit of measuring the amount of pull or push a force such as gravity produces between two masses.
What is newton's?
100
Are mass and weight the same thing?
What is no?
100
Who concluded that objects accelerate steadily as they fall and that an objects weight, or mass, does not affect how fast it accelerates when falling?
Who is Galileo?
100
If you drop a hammer and a feather on the moon which one would fall first and why?
What is neither, because there is no air so there is no air resistance?
200
This is how an object is pulled to Earth.
What is Gravity?
200
How do we find an object’s weight in newton's?
What is by multiplying an object’s mass in kilograms by 9.8?
200
Why do you weigh different amounts on different planets?
What is the pull of gravity is different on each planet?
200
Objects with a large mass are pulled on by gravity with more force, but they also have more of this.
What is inertia?
200
A rubber ball is dropped off a tall tower. After one second it will be traveling this fast.
What is 9.8 m/s?
300
Gravity is an attraction between the mass of what?
What is Earth and the mass of an object?
300
What is the weight in Newton’s for an object with a mass of .4kg?
What is 3.92 N?
300
Do heavy objects fall faster than lighter objects?
What is no?
300
A combination of the Moon's inertia and the force of gravity between Earth and the Moon keeps the moon doing what?
What is orbiting the Earth?
300
What causes objects to fall?
What is the force of gravity between Earth and the objects?
400
Ignoring what, all objects fall at the same rate?
What is air resistance?
400
What is the weight in Newton’s for an object with a mass of 6 kg?
What is 58.8 N?
400
The piece of balled paper in the "Does weight affect how fast an object falls?" lab fell faster due to what?
What is less air resistance?
400
Added weight is helpful in cycling because it provides this.
What is traction?
400
Is the moon's acceleration expressed as a change in speed of a change in direction?
What is change in direction?
500
All objects accelerate to the ground at what rate?
What is 9.8 meters per second each second?
500
How many kilograms is an object if its weight in Newton’s is 19.6?
What is 2 kg?
500
Objects of different masses fall at the same rate due to what?
What is there is a greater pull of gravity on the object with greater mass, but the acceleration is the same?
500
What does it mean to say that the law of gravity is universal?
What is that it applies to any two objects?
500
Two planets in a distant solar system have the same radius but different masses. On which world would you weigh more and why?
What is the planet with greater mass, because there is a greater pull of gravity?
