Teacher Explanation Pull to Earth Why do the people on the Earth remain on it, even when they are upside down? Gravity the force that attracts an object towards the centre of the Earth, or towards any other physical body having mass.

Mass and Weight Mass Weight Teacher Explanation Mass and Weight Mass This is the amount of matter that an object contains. This is measured in kilograms. Weight This is a measure of the force of gravity acting on an objects mass. This is measured in Newton's.

Quick Check Define the term “Gravity”. Learning Activity Quick Check Define the term “Gravity”. Describe the difference between Mass and Weight. Draw a picture to show the forces acting on people, standing on the Earth.

What are the two different types of satellites? Gravity Developing: Define the difference between mass and weight. Secure: Calculate the force of gravity on different planets. Exceeding: Illustrate the forces of gravity on Earth. Entrance Activity What are the two different types of satellites?

Student reading activity Man on the Moon On Earth, Neil Armstrong had a weight of 920N and a mass of 92kg. When Neil went to the moon he found he could jump significantly higher and further. This was due to him having a reduced weight. The gravity on the moon is about a 1 6 of the gravity on earth, so although his mass stayed the same, he weighed significantly less due to the reduced gravity. Student reading activity

Calculating Weight Weight (N) = Mass(kg) x Gravity(N/Kg) Teacher Explanation Calculating Weight Weight (N) = Mass(kg) x Gravity(N/Kg) Mr Helps has a mass of 88kg. On Earth, gravity measures 9.81N/kg. Calculate his weight on Earth. Weight (N) = Mass(kg) x Gravity(N/kg) Weight (N) = 88(kg) x 9.81(N/kg) 863.28 (N) = 88(kg) x 9.81(N/kg)

Learning Activity Different Planets Arrange the planets in order of gravitational strength. Calculate the weight of Mr Helps on each of the planets.
