A force is required for any change in an object's motion to occur.

True
False

True

Explanation:

an object in motion stays in motion unless acted upon by another force

Answer/Explanation:

True. A force is what causes a movement in the first place. In order for an object to change motion a different force must be applied such as its opposing force.

Natural force: Thrust

Opposing force is drag.

Other forces are gravity and lift.

The opposing force will reverse the motions direction, the other forces will just change the direction without reversing.

Below is the

W = mg 

W = ? 
m = 670 
g = ? 

radius of Neutron star = 11.5 km = 11,500 meters 

We need to find g on the Neutron star, so: 
g = GM/r^2 
g = 6.67 x 10^-11 x 1.99 x 10^30/11,500^2 
g = 1 x 10^12 

W = 670 x (1 x 10^12) 
W = 6.7 x 10^14 N
