Description
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
