Physical Science Mass and Weight Worksheet Define Mass – Amount of matter in an object Define Weight Weight is the amount of gravitational pull on an object

Describe what will happen (if anything) to mass and weight when you go to the moon. Mass will remain the same and weight will change. Why would this happen? Because the moon is smaller than Earth then it has less gravity which will result in less weight. Matter will never change on the moon because it’s based on matter

Find the weight of a 60 kg astronaut on earth. Weight (W) = Mass (m) x gravity (g) W = mg Mass is measured in kilograms (kg) Gravity on earth is a constant: 9.8 m/s2 Weight is measured in Newton’s (1 N = 1 kg  m/s2 ) Answer: 60 kg x 9.8 ms/s squared = 588 N

a. Find the weight of the same object on a planet where the gravitational attraction has been reduced to 1/10 of the earth’s pull. Show all work. 9.8 x 1/10 = .98 60 Kg x .98 m/s2= 58.8

Astronauts train in simulators that allow them to experience conditions of zero gravity, similar to what they will experience in space. Which of the following describes why the astronauts float inside the simulators? A. There is no air pressure. B. Their mass becomes zero. C. Their weight becomes zero. D. Their mass is equal to their weight.

C

Kanya calculates what her weight would be on every planet in the solar system. She determines her weight on Jupiter would be more than double her weight on Earth. What does this weight difference indicate about Jupiter? A. Objects gain mass when they go to Jupiter. B. Objects lose mass when they go to Jupiter. C. The gravitational pull on Jupiter is less than on Earth. D. The gravitational pull on Jupiter is greater than on Earth.

D

Serena is writing a computer application to calculate weight on any planet in the solar system. Which of the following factors should she include? A. mass of the object B. gravity on the planet C. mass of the object and gravity of the planet D. mass and volume of the object, gravity on the planet
