By Miss Lobb

2. Pre-test “Get Moving”
• 1. What is a force?
• 2. What are the two categories (types) or
forces?
• 3. What can a force do to a soccer ball?
(effects)
• 4. What is gravity?
• 5. What is the difference between mass
and weight?
• 6. What units do we use to measure mass
and weight?

3. Pre-test “Get Moving”
• 7. Give examples where friction is
– helpful
– a nuisance.
• 8. What is speed, and how can you
measure speed using a tape measure and
a watch?
• 9. What is a ticker timer?
• 10. What does the gradient (or slope) of a
distance vs. time graph tell you?

4. Answers
• 1. What is a force? – A Push or a Pull
• 2. What are the two categories (types) or forces?
– Contact and non-contact
• 3. What can a force do to a soccer ball? (effects)
– Accelerate it, slow it down, move it from its
current trajectory, change its shape
• 4. What is gravity? – It is a force. The pull of an
object towards the centre of earth.
• 5. What is the difference between mass and
weight? – Weight is a force measured in (N).
Mass is the amount of an object measured in Kg

5. Answers
• 6. What units do we use to measure mass and weight? -
Mass Kg, Weight N
• 7. Give examples where friction is
– helpful
– a nuisance.
• 8. What is speed, and how can you measure speed
using a tape measure and a watch? S = D / T
• 9. What is a ticker timer? – A devise in which to measure
speed
• 10. What does the gradient (or slope) of a distance vs.
time graph tell you? - How fast and object is moving.
