Mass vs. Weight
What is the definition of mass?
What is the amount of matter in an object?
What is the formula for calculating the volume of a rectangular prism?
L X W X H
What are some examples of physical properties of matter?
What are color, mass, volume, density, shape, and state (solid, liquid, gas)?
What are the three common states of matter?
What are solid, liquid, and gas?
What force pulls all objects toward the center of the Earth?
What is Gravity
How is weight different from mass?
hat is weight is the gravitational force acting on an object, while mass is a measure of the object's matter?
If a rectangular object measures 6 cm by 4 cm by 3 cm, what is its volume?
What is 72 cm³?
How do you calculate the density of an object?
D=M/V
In which state of matter do particles have a definite shape and volume?
What is a Solid
What is the acceleration due to gravity on Earth?
What is 9.8m/s2
True or False: An object's mass changes when it is taken to another planet.
What is false
How do you find the volume of an irregular object?
What is by using the water displacement method?
If an object has a mass of 500 grams and a volume of 250 mL, what is its density?
What is 2 g/mL?
What happens to the molecular structure of water when it evaporates?
What is the molecules gain energy and spread apart, changing from liquid to gas?
How does gravity affect the weight of an object on the Moon compared to Earth?
What is the weight is less on the Moon due to weaker gravitational pull?
If an object has a mass of 80 kg on Earth, what would its weight be in Newtons? (Use 𝑔=9.8 m/s2g=9.8m/s2)
What is 784 N? (Calculation: 80 kg×9.8 m/s2=784 N80kg×9.8m/s2=784N)
If a cube has a side length of 5 cm, what is its volume?
What is 125 cm³?
Explain how the density of a substance can be considered a physical property and why it is important in identifying materials.
What is density is a characteristic property that helps identify substances, as each material has a specific density that remains consistent regardless of sample size?
What is the term for the process of changing from a solid to a liquid?
What is Melting
If you drop a feather and a hammer on the Moon, what will happen?
What is they will fall at the same rate due to the lack of air resistance?
How does the concept of mass and weight apply to objects in free fall in a vacuum?
They would fall at the same rate
A cube has a mass of 500 grams. One side of the cube measures 5 cm. Calculate the density of the cube.
density of the cube is 4 g/cm³.
A liquid has a density of 1.5 g/cm³. If you drop an object with a density of 1.2 g/cm³ into this liquid, what will happen and why?
What is the object will float because its density is less than the density of the liquid?
Describe the molecular changes that occur during the process of condensation.
What is gas molecules lose energy, slow down, and come closer together to form a liquid?
Explain how the gravitational force between two objects changes as the distance between them increases.
What is the gravitational force decreases as the distance increases, following the inverse square law?
