MASS AND WEIGHT
Do larger objects always have more mass than smaller objects ?
No, larger objects always don't have to have more mass than smaller objects because for example a stone has more than a feather
Do heavier objects fall to the ground faster than lighter objects?
No - the two objects will fall at the same rate provided they experience the same gravitational acceleration. In an atmosphere however, a large non-aerodynamic object (say, a parachute) could fall much more slowly than a light, aerodynamic object (a small ball bearing, perhaps).
Will a hammer or a feather fall to the ground faster on Earth?
In an environment with air, the hammer will fall more quickly. The feather will have a greater amount of aerodynamic resistance on it preventing it from falling, proportional to its mass, than the hammer will.
Would a person’s weight change if he or she were standing on different planets? Why?
Yes, his weight its gonna change because the gravity of others planets its different from that of the Earth
Would a person’s mass change if he or she were standing on different planets? Why
Mass stays the same regardless of location and gravity. You would have the same mass on Mars or Jupiter as you do here on Earth. Your weight is different on other planets due to gravity. However, your mass is the same everywhere!
Is the size of an object a good way to predict its mass?
Yes, the size a good way to predict the mass of that object because you have to multiply it sizes to calculate the mass
The fourth with out the hammer measures 66 cm3 and with the hammer measures 70 cm3
The first with out the dinosaur measures 5 cm3 and with the dinosaur measures 6 cm3
The fifth picture with out the object measures 44 cm3 and with the object measures 53 cm3
The second with out the fish toy measures 32 cm3 and with the fish toy measures 40 cm3
The third one with out the human toy measures 3,2 cm3 and with the human toy measures 5,1 cm3
The last picture with out Sponge Bob measures 51 cm3 and with Sponge Bob measures 52 cm3
DISPLACEMENT METHOD
I think the displacement method is effective because of this form is more easy to calculate the volume of an object
