Students will be able to
- identify weight as a force that acts on an object with mass in a gravitational field,
- recognize that acceleration due to gravity in meters per square seconds (m/s2) is equal to gravitational field strength in newtons per kilogram (N/kg),
- calculate weight forces where acceleration due to gravity may vary,
- recognize that variation in weight due to variation in acceleration due to gravity does not involve variation in mass.
Students should already be familiar with
- Newton’s first law of motion,
- Newton’s second law of motion.
Students will not cover
- Newton’s third law of motion,
- Newton’s law of universal gravitation.
