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.
From the previous question, the object is accelerating away from the centre that it is spinning around.
The name of the resultant force that causes the object to accelerate is called [blank_start]centripetal force[blank_end].
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.
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.
To increase the stability of an object, you can [blank_start]lower the centre of mass[blank_end].
