G3 Science (Physics): Force and Pressure structured questions
Marked practice for Science measurement and pressure: unit and area conversions, reading scales, choosing instruments, density and contact pressure.
Learning objectives
- Distinguish contact forces from non-contact forces
- State that mass measures the amount of matter in a body
- Describe a gravitational field as a region where a mass experiences gravitational force
- Define gravitational field strength as gravitational force per unit mass
- Apply weight = mass × gravitational field strength
- Distinguish mass from weight
- Apply density = mass ÷ volume
- Define pressure as force per unit area
- Apply pressure = force ÷ area
