## Resource summary

### Question 1

Question
If 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.
• speed
• accelerating
• direction
• velocity
• acceleration

### Question 2

Question
From the previous question, the object is accelerating away from the centre that it is spinning around.
• True
• False

### Question 3

Question
The name of the resultant force that causes the object to accelerate is called [blank_start]centripetal force[blank_end].
• centripetal force
• centrifugal force
• centrifloral force
• gravity
• air resistance

### Question 4

Question
How does the resultant force on the object change when it slows down?
• It is increased/it increases.
• It is reduced/it decreases.
• It stays the same.
• The resultant force is not affected by the changing speed.

### Question 5

Question
What is meant by the centre of mass?
• A fast-food restaurant.
• The point at which the mass can be considered to be concentrated.
• The heaviest part of an object which has the biggest weight.
• An object with the highest mass.

### Question 6

Question
To increase the stability of an object, you can [blank_start]lower the centre of mass[blank_end].
• lower the centre of mass
• increase the mass of an object
• raise the centre of mass
• decrease the mass of an object
• make it weightless
• break it
