1. Define Mass –. 2. Define Weight –. 3. Describe what will happen (if anything) to mass and weight when you go to the moon. a. Why would this happen? 4. Find the weight of a 60 kg astronaut on earth. 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. 5.
Mass is a measure of the amount of matter (stuff) in an object. It is measured in kilograms (kg) Weight is a force and it is the pull of gravity acting on an object. It is measured in Newtons. Collect a 20N spring balance and a set of 100 g masses. Predict the weight (force of gravity) on 100 g. Record this in the table.
m = mass (The SI unit of mass is the kilogram, kg) g = acceleration due to gravity (The SI unit of g is m/s 2 ) w = weight (The SI unit of w is kg m/s 2 or Newton)
Practice Problem Set F=ma FORCE = MASS x ACCELERATION Plug in the given values for Force/Mass/Acceleration to solve. Remember, mass is in kg - - force in in N (newtons) - - acceleration is in m/s 2 1. How much force is needed to accelerate a 66 kg skier at 2 m/sec 2? 2.
Weight Practice Problems. 1. Weight is a measure of both _______________ and _________________. It is measured on a _____________ _____________. The units for weight are ________________. The formula for finding weight is: W=_________ ___ ______________. 2. Mass is a measure of how much _______________ a substance is made of.
Mass is a measure of the amount of matter in an object. Mass is not related to gravity. The mass of an object does not change when it is moved from one place to another. Mass is commonly measured in grams or kilograms. Weight is a measure of the gravitational force between two objects.
