<h3>What is a Vector ?</h3>
A vector is an object that has both a magnitude and a direction
- Geometrically, we can picture a vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction.
- The direction of the vector is from its tail to its head.
- Examples of vectors in nature are velocity, momentum, force, electromagnetic fields, and weight.

Answer:
In space there is no air resistance. on earth there is
in space there is no opposite forces acting on stopping the ball, so if you throw it it will go on forever.
on earth there is air resistance and gravity, this will pull the ball towards the ground and slow it down.
Chemical properties are observed when matter or substance changes to form a new kind of matter or substance.
<h3>What is Chemical properties?</h3>
This is the term used to describe the ability of a substance or matter to react and form new substance. Chemical properties are used during chemical reaction to be able to control the reaction and get a certain product
we can conclude that chemical properties are observes during chemical reaction to ascertain the new substance or matter to be formed

- Weight = (mass) x (gravity)
6.86 N = (mass) x (9.8 m/s²)
Mass = (6.86 N) / (9.8 m/s²)
Mass = (6.86 kg-m/s²) / (9.8 m/s²)
Mass = (6.86/9.8) kg
Mass = 0.7 kilogram
<em>I would use the 500-gram weight and the 200-gram weight,</em> and hang them both from the end of the thread. Then the total mass on the end of the thread is 700 grams. When I take it to Earth, it will weigh 6.86 N .
Solid and liquids are much more denser than gas because their molecules are close to each other and with that the molecules of them can't move that freely unlike the gas molecules. Also, because of being near to each other the molecules of solid and liquids became heavy making them dense.
