You are wrong
A projectile has no motor/rocket on it, so all of its momentum is given to it as it is launched. An example of a projectile would be pen that you throw accross a room. A rocket or missile does have a motor/rocket on it so it can accelerate itself while moving and so resist other forces such as gravity. answer in mechanics point of view projectile dont have any particular shape it is a point mass. whereas rocket has a particular shpe and hence it has center of gravity situated at particular point on its body.Therefore rocket motion comes under kinetics and projectile comes under kinematics
angular momentum is the measure of angular motion in a body.
momentum is product of moment of inertia and angular velocity. There is always a 90 degree phase difference between velocity and acceleration vector in circular motion therefore angular momentum and acceleration can never be parallel
I will guess: bearings. the more fluid the motion, the less friction. or the joint could be a silicon soft plastic type that flex and allow fluid like motion while maintaining strength.
An Oscillating motion is one that moves forwards and backwards in an arc or circle repeatedly. is called oscillatory motion ... by : anushka rai
Without air friction, the horizontal component of the velocity will be constant. The vertical component of the velocity will be a maximum at the lowest point in its motion and at a minimum at the highest point in its motion. Therefore the minimum is at the highest point in its motion- Potential energy max Kinetic Energy min and the maximum is at its lowest point in the motion- KE is max PE min
45 degrees is the furthest one
-- In what direction should a projectile be launched in order to achieve the maximum range ? -- Toward 45 degrees above the horizontal.
hypothesis on projectile motion
Because a projectile by definition, is in motion.
Projectile motion has two components horizontal motion and vertical motion. Gravity affects only the vertical motion of projectile motion.
motion of a projectile
work, momentum, impulse, kinetic and potential energy, elastic and inelastic collisions, projectile motion, Newton's three laws of motion, velocity, acceleration, displacement, and forces.

Gravity
A feather falling in a vacuum is not considered as a projectile motion. Gravity, which is absent in a vacuum, is one of the components of projectile motion.
