About This Topic

Students will understand gravity as a universal attractive force, differentiate between mass and weight, and calculate weight using gravitational field strength.

Key Questions

1. Explain gravity as a force of attraction between any two objects with mass.
2. Differentiate between mass and weight, and explain why weight can change but mass remains constant.
3. Calculate the weight of an object given its mass and the gravitational field strength.
