Gravitational is the force of 2 object or body like the sun a earth and gravity is the force on 1 object or body for instance an apple falling
Example of scalar: speed. Example of vector: velocity
Explanation:
In physics, there are two types of quantities:
- Scalar: a scalar quantity is a quantity having only magnitude, so it is just a number followed by a unit. Examples of scalar quantities in physics are:
Mass
Time
Speed
- Vector: a vector quantity is a quantity having both a magnitude and a direction. Examples of vector quantities in physics are:
Force
Acceleration
Velocity
The two types of quantities can be used in the same event, but in a different way. One of the most common example is the difference between speed and velocity.
In fact, let's consider an object moving in a uniform circular motion: it means that it is moving in a circle at a constant speed. The speed of the object measures only how fast the object is moving, but without telling anything about its direction of motion. The velocity, viceversa, also takes into account the direction of motion, and exactly for this reason, the velocity in a uniform circular motion is not constant, because the direction (it is a vector) is constantly changing. So, in a uniform circular motion, the speed is constant but the velocity is not.

Answer:
The tension in the string is quadrupled i.e. increased by a factor of 4.
Explanation:
The tension in the string is the centripetal force. This force is given by
m is the mass, v is the velocity and r is the radius.
It follows that 
, provided m and r are constant.
When v is doubled, the new force, 
, is
Hence, the tension in the string is quadrupled.
The kenitc energy of the bullet lowers as it keeps going up.
Because gravity is pushing the bullet down as the bullet goes up.
I'm pretty sure that the way to put this answer.
Answer:
The change in momentum experienced by the bowling ball is 96 kgm/s.
Explanation:
Given;
mass of the bowling ball, m = 12 kg
velocity of the bowling ball, v = 8 m/s
time of motion, t = 10 s
The change in momentum experienced by the bowling ball is equal to the impulse experienced by the bowling ball.
ΔP = J = F x t
Therefore, the change in momentum experienced by the bowling ball is 96 kgm/s.
