Unformatted text preview: familiar… • Weight = Force • Weight is measured in N (newtons) Putting it all together • The apple has mass (kg) • It gets pulled to the ground at a force (this can be measured in Newtons) = WEIGHT • The earth’s gravitational field strength pulls the apple towards it How can we calculate weight? • We can use an equation we already know to help us: • g ( gravitational field strength ) = force / mass • If Force = Weight • Weight = Mass x g ( gravitational field strength ) • Memorise: W = m X g This powerpoint was kindly donated to www.worldofteaching.com http://www.worldofteaching.com is home to over a thousand powerpoints submitted by teachers.
