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.
Answer
  • 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.
Answer
  • 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].
Answer
  • 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?
Answer
  • 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?
Answer
  • 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].
Answer
  • 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
