  1. 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 –.

  2. weight A reel of copper wire is labelled length 30 m and diameter 2 mm . A student calculates the volume of the copper wire. Which instruments does he use to measure accurately the leng th and the diameter of the wire? Which row correctly shows examples of a vector quantity and a scalar quantity?

  3. 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.

  4. 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.

  5. 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.

  6. Lab #1 Measurement of length, Mass, Volume and Density . Readings. Before you begin this laboratory read chapter 1 of the textbook. Objectives. After completing this lab, you will be able to: Make measurements to the nearest 1/10 of a millimeter using a meter stick. Use a vernier caliper to make measurements to the nearest 1/10 of a millimeter.
