1If an object is spinning around a point at a constant [blank_start]speed[blank_end], the object is [blank_start]accelerating[blank_end]. This is because the object is changing [blank_start]direction[blank_end]. This means that the [blank_start]velocity[blank_end] is changing, and as [blank_start]acceleration[blank_end] is the rate of change of velocity, the acceleration changes too.
- Aspeed
- Baccelerating
- Cdirection
- Dvelocity
- Eacceleration
2From the previous question, the object is accelerating away from the centre that it is spinning around.
- AVerdadero
- BFalso
3The name of the resultant force that causes the object to accelerate is called [blank_start]centripetal force[blank_end].
- Acentripetal force
- Bcentrifugal force
- Ccentrifloral force
- Dgravity
- Eair resistance
4How does the resultant force on the object change when it slows down?
- AIt is increased/it increases.
- BIt is reduced/it decreases.
- CIt stays the same.
- DThe resultant force is not affected by the changing speed.
5What is meant by the centre of mass?
- AA fast-food restaurant.
- BThe point at which the mass can be considered to be concentrated.
- CThe heaviest part of an object which has the biggest weight.
- DAn object with the highest mass.
6To increase the stability of an object, you can [blank_start]lower the centre of mass[blank_end].
- Alower the centre of mass
- Bincrease the mass of an object
- Craise the centre of mass
- Ddecrease the mass of an object
- Emake it weightless
- Fbreak it
