ANSWERS TO FORCES & MOTION QUIZ QUESTIONS:
Teaching is about selling fish. Learning is about CATCHING fish. (Anon)
Q1. Comparing Weights on A Pulley:
The purpose of this task is to help students understand forces acting in a pulley system.
Q2. Hitting A Golf Ball - Forces on Ball In Flight:
The purpose of this task is to discover the forces acting on a golf ball in flight.
Q3. Toy Cars - Slope & Energy:
Toy cars – 5EC071 This open-ended task requires students to relate the height of a toy car on a slope to the energy it will have at the bottom of a slope. They describe the forces acting on the toy car and explain its motion in terms of varying frictional forces on different surfaces.
Q4. Toy Cars - Slope, Weight & Energy:
Toy cars - An open-ended task requires students to relate the height and weight of a toy car on a slope to the energy it will have at the bottom of a slope. They describe the forces acting on the toy car and explain its motion in terms of varying forces.
Q5. Toy Cars - Slope & Surface Friction:
Toy cars – An open-ended task requires students to relate the height of a toy car on a slope to the energy it will have at the bottom of a slope. They describe the forces acting on the toy car and explain its motion in terms of varying frictional forces on different surfaces.
Q6. Forces On A Ball Thrown Into The Air (a projectile):
Throwing a ball – The purpose of this task is to understand forces acting on a ball that has been thrown up into the air.
Q7. Pushing Two Cars Up A Slope:
Pushing the car - The purpose of this task is to investigate forces acting on a car being pushed up a slope.
Q8. Falling Down A Hole Through The Earth:
The purpose of this task is to consider the shape of the Earth, where we live on it and of objects falling down towards the Earth.
Q9. Is There Gravity On The Moon:
The Moon – The purpose of this task is to discover morea about force on the Moon. This task asks students whether an object will float, fall or rise when released by an astronaut on the Moon.
Q10. Rocket Blast-off From Multiple Planets:
Gravity - The purpose of this task is to investigate gravity on planets. This task requires students to consider whether distance from the Sun and size of planet affect gravity on that planet. Do the videos in the link below give you any clues about the gravity on the Moon compared with gravity on the Earth:?
Q11. How Does Rain Fall:
It's raining - The purpose of this task is to diagnose misconceptions about the shape of the Earth, our position on Earth and objects falling to the centre of the Earth. This task requires students to select a diagram representing how they believe it to be, from five drawn by children.
Q15. How Bicycle Brakes Work:
Bicycle brakes – This objective task requires students to explain the result of push-pull actions on a bicycle and cyclist. Students are required to show an understanding of friction, air resistance and tyre grip, all in simple terms. There are some great extended activities - ask your teacher!
Q16. Remote Control Toy Cars & Surface Friction:
Friction effects – This objective task requires students to consider the forces acting on a car on different surfaces. Frictional effects are also considered (is friction a force?).
Q17. Pushing With A Steady Hand (Constant Velocity With Friction):
Investigating forces and friction -let’ s have a look at an example of a book being pushed at constant velocity across a desk top:
Q18. Living With Gravity On Other Planets:
Gravity on other planets – This open-ended task requires students to research the magnitude (size) of gravity on the surface of other planets. Students then use this information to compare some aspects of ‘living’ on other planets.
