Collect graph paper (or use your own) before you start this task. This graph MUST be handed in at the end of the E-day session in order for it to be marked.
To type answers that have superscripts, please follow this format (using ^ to indicate superscript):
For scientific notation: e.g. One hundred thousand (100 000) would be typed like this: 1,0 x 10^5
For units such as metres per second squared, type is like this m.s^-2

Watch the slide presentation embedded below on mass and weight and then answer the questions that follow. To go to the next slide click on "next" in the bottom right hand corner.
Here is the direct link to the presentation if yours is not working in the Formative below.

Read the following information from your textbook pg 213:
Consider the masses of the following planets in our solar system:
Order them from smallest mass to greatest mass
Venus
Mars
Mercury
Neptune
Earth
Order the planets from smallest to largest (diameter)
Mercury
Neptune
Venus
Mars
Earth
The following data was collected on a particular planet during an investigation to calculate the acceleration due to gravity (g) on that planet. The weight of each mass was measured and the results were recorded in the table below:
Plot a graph of weight vs mass on your piece of graph paper. Draw a line of best fit.
On the back of your graph, calculate the gradient of your line. Be sure to show the values you used ON YOUR ACTUAL GRAPH (circle them) and also include the appropriate unit for this gradient (as per the graph)
Watch the video on Newton's law of universal gravitation. Here is the link if this video is not working on Formative: video
Newton's law of universal gravitation is described below too:
What happens to an object's weight when it is taken to a location with higher gravity, such as a planet with greater mass?
What is the acceleration due to gravity (g) on this planet? Use the appropriate unit.
Hence, use the following data to identify the planet used in this investigation:
