What causes spin in a projectile during its projectile motion?
The spin is forced on to the bullet or shell by grooves in the gun barrel, this is to take advantage of the fact that the axis of a rotating object will tend to remain parallel, this , in effect keeps the shell or bullet in a good aerodynamic profile, without tumbling (which absorbs energy). These grooves are known as rifling and so any weapon which has those grooves in the barrel is said to be rifled.
Why can a projectile maintain a constant horizontal speed when neglecting air resistance?
When air resistance is neglected, there are no horizontal forces acting on the projectile to change its speed. According to Newton's first law, an object in motion will remain in motion with a constant velocity unless acted upon by an external force. Therefore, the projectile will maintain a constant horizontal speed in the absence of air resistance.
What happens when you increase the horizontal velocity to the maximum in a projectile motion?
Increasing the horizontal velocity to the maximum in a projectile motion will cause the object to travel further horizontally before hitting the ground. This is because the horizontal velocity determines how far the object will travel in the horizontal direction before gravity pulls it down. The vertical motion of the object will remain the same, but the increased horizontal velocity will result in a longer horizontal distance traveled.
What quantities remain constant in projectile motion?
All that I can think of are: 1.) Gravity 2.) Wind 2.A) wind speed 2.B) direction of wind 3.) Angle of trajectory 4.) Initial speed of projectile 5.) Material through which projectile travels (as in density) 6.) Mass of projectile 7.) Spin 7.A) speed of spin 7.B) axis/axes spining occurs on 8.) Shape of projectile 9.) Temperature of medium projectile is in 10.) Size of projectile (as in height, width, and depth) 11.) Weighting of projectile 12.) Obsturctions to projectile's path In a vaccuum, though, these are the variables: 1.) Speed of object 2.) Obstructions in path 3.) Gravity
Why horizontal motion is constant?
Horizontal motion is constant when there are no external forces acting on an object in that direction. According to Newton's first law of motion, an object in motion will stay in motion at a constant velocity unless acted upon by an external force. This is why horizontal motion can remain constant when there is no acceleration or deceleration.

As a projectile shot at an upward angle rises and falls what happens to its horizontal component of its velocity if you neglect air resistance?
If there wouldn't be air resistance and gravity is the only thing that is effecting the projectile, the projectile will start to fall but it horizontal velocity will remain the same. So it would slow down, it would only change height.
What will be range of projectile if its initial speed is doubled?
Doubling the initial speed of a projectile will quadruple its range, assuming all other factors remain constant. This is because the range of a projectile is directly proportional to the square of its initial speed.
An object at rest will remain at rest and an object in straightline motion will remain in straightline motion unless acted upon by a n?
Force
Why is the book placed on the table remain in state of rest while force of gravity is applied?
An object at rest tends to remain at rest - an object in motion tends to remain in motion.
How does the first Law of Motion relate to the catapult?
All three play a part. The first applies as the arm swings and launches the projectile. The arm continues to move until it is stopped by the retaining bar and the projectile continues to move until gravity pulls back down or it impacts a structure. The second law is shown by the projectile. A big heavy rock goes slow, a small light rock flies fast. The third comes into play as the catapult launches the projectile it pushes down on the ground and slightly backward. The projectile itself uses the third law when it impacts.
Do molecules stay the same during physical change?
Yes, during a physical change, molecules remain the same. The arrangement and motion of molecules may change, but the actual atoms that make up the molecules do not change.
What is the tendency of an object at rest to remain at rest or an object in motion to remain in motion is called?
This tendency is called inertia, as described by Newton's First Law of Motion. Inertia is the resistance of an object to changes in its state of motion.
