1. The weight of a 1 kg mass at the surface of the Earth is… g = 9.8 m/s 2. Known : Mass (m) = 1 kg. The acceleration due to gravity at the surface of the Earth (g) = 9.8 m/s 2. Wanted: weight (w)
Physical Science Mass and Weight. Use the following formula to solve for weight: 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 the following questions – show ALL WORK and UNITS. 1. Define Mass –.
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.

Use the weight formula. W = mg. Solve for mass. Substitute one newton for weight and one standard earth gravity for gravity.
In these practice problems we will either use F=ma or our 1D motion acceleration equations to solve force problems. 1. What is the acceleration of the 15 kg box that has 500 N of force applied to the right? See Answer. a = 33.33 m/s2 Right. 2. What is the acceleration of the 25 kg box that has 50 N of force applied to the right? See Answer.
How do we define mass, weight, and gravity? How are mass, weight, and gravity related? The weight equation W = mg shows that an object’s weight (in newtons) is equal to its mass (in kilograms)
