Ms. Howard's science class looked at the group of stars called the Big Dipper, They watched it in the early evening during fall
and spring. This is what
they saw:
Fall- upright and low in the sky
Spring - upside down and high in sky
Why does the position of the Big Dipper change during the year?
O A Earth revolves around the Sun,
OB. The position of the Moon is different in the fall than in the spring.
O C. The Big Dipper is made of different stars in the fall than in the spring.
OD. The Big Dipper moves toward Earth in the fall and away in the spring.

To solve this problem it is necessary to apply the concepts related to the Moment. The moment in terms of the Force and the time can be expressed as
F = Force
At the same time the moment can be expressed in terms of mass and velocity, mathematically it can be given as
Where
m = Mass
Change in velocity
Our values are given as
By equating the two equations we can find the Force,
Therefore, the net average force will be:
The negative symbol indicates that the direction of the force is upwards.
