  1. 6E Balanced and unbalanced forces What do you know?

  2. 1. What can you use to measure a force? • A ruler • A forcemeter • A tape measure • A magnet Response Grid

  3. 2. What are the units for force? • Kilograms • Grams • Newtons • Centimetres Response Grid

  4. 3. What causes weight? • The Earth attracting objects • The Earth repelling objects • The Earth and an object attracting each other • Forcemeters Response Grid

  5. 4. Which diagram is correct? • Large weight Small weight • Large weight Small weight • Large weight Small weight • Large weight Small weight Response Grid

  6. 5. Which statements is true? • There is an upwards force from the table that is a bit less than the weight • There is an upwards force from the table that is the same size as the weight • There is an upwards force from the table that is a bit more than the weight • There is no upwards force from the table Response Grid

  7. 6. What happens when you stretch an elastic band • The more you stretch it, the harder it pulls back • The more you stretch it, the less it pulls back • The force from the elastic band does not change • It breaks Response Grid

  9. 7. What is upthrust? • A sideways force on things in water • A downward force on things in water • An upwards force on things in water • Any upwards force Response Grid

  10. 8. Jenna weighs a stone in air and water. What is the upthrust on the stone? • 2 N • 4 N • 6 N • 8 N Response Grid

  13. 11. What are the forces on a falling object? • Weight downwards and air resistance upwards • Weight downwards and air resistance downwards • Weight upwards and air resistance downwards • Weight upwards and air resistance upwards Response Grid

  14. 12. How can you increase the air resistance of a parachute? • Make the parachute smaller • Make the parachute bigger • Put longer strings on it • Change the colour Response Grid
