What is the formula for mass and weight?
w = m/g
w = m - g
w = mg
w = m + g
What do you use to measure mass?
Newton Meter
Spring Balance
Weighing Scale
Beam Balance
What is the formula for density?
density = mass / volume
density = volume / mass
density = mass x volume
density = mass + volume
What is the SI Unit for Density?
g / cm3
g / m3
kg / m2
kg / m3

Your mass is the amount of matter, or "stuff", in your body. How would your mass on the Moon compare to your mass on Earth?
Greater on the Moon
Less on the Moon
Same on Earth and the Moon
Your weight is the pull of gravity on your body. Suppose you step on a bathroom scale on the Moon. How would your weight on the Moon compare to your weight on Earth?
Greater on the Moon
Less on the Moon
Same on Earth and the Moon
Which Celestial body has the strongest gravity, Earth, the Moon, Mars, or Jupiter?
Earth
The Moon
Mars
Jupiter
Predict:
On which planet or Moon do you think the 5-kg mass will weigh the most? Least:
The 5-kg mass will weigh the least on Jupiter and the most the moon
The 5-kg mass will weigh the most on Jupiter and the least on the moon
True or False -
Mass and weight are the exact same thing.
true
false
What is the definition of MASS?
Anything that has mass and takes up space.
The measure of the gravitational pull on an object.
That amount of matter in an object.
The measure of the gravitational pull on an object is called:
weight
mass
matter
