Answer:
The work could be either positive or negative, depending on the direction the object moves
Explanation:
Physics is everything in life technically. and there is a lot of types of physics. also it is math and reading mixed together.
For the same reason that you can skate around a curve at constant speed but not with constant velocity.
The DIRECTION you're going is part of your velocity, but it's not part of your speed.
If the DIRECTION changes, that's a change of velocity.
The object doesn't have to change speed to have a different velocity. A change of direction is enough to do it.
And any change of velocity is called acceleration.
Answer:
24N
Explanation:
Calculation for what his weight would be
Let his WEIGHT on the surface of earth be 600 and Let the RADIUS be 25 which is (5^²) because we were told that the radius is FIVE TIMES larger than earths
Now let calculate his weight using this formula
Weight=Weight on Earth/Radius
Let plug in the formula
Weight=600N/5^²
Weight=600N/25
Weight=24N
Therefore his weight would be 24N
