Worked Solution & Example Answer:Which row shows two scalar quantities? A gravitational potential gravitational field strength B mass gravitational potential C gravitational field strength weight D weight gravitational potential - AQA - A-Level Physics - Question 8 - 2019 - Paper 2
Step 1
B mass gravitational potential
Answer
In this option, 'mass' is a scalar quantity because it has magnitude but no direction. 'Gravitational potential' is also a scalar quantity, as it describes the potential energy per unit mass at a point in a gravitational field, again without a directional component.
