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, Weight & Density. 1 A brick is placed on a newton meter and then on a beam balance. 3 The mass of a stone is found on Earth using a pan balance. The weight of the stone is found using a newton meter.
Weight is a force and it is the pull of gravity acting on an object. It is measured in Newtons. Experiment 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. Test your answer and record the measured weight.
Density is calculated using the equation: density = mass ÷ volume. Density is measured in kg/m³ or g/cm³. The volume of water displaced by a submerged object is equal to the volume of the object. The dimensions of a regular cuboid can be measured accurately with Vernier callipers.
