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

The main difference between turbojets and rocket engines is the fact that?
the main difference between turbojets and rocket engines lies in their method of generating thrust. Turbojets rely on atmospheric oxygen to combust fuel and generate thrust, making them dependent on the surrounding air. In contrast, rocket engines carry both fuel and an oxidizer, allowing them to operate in the vacuum of space where there is no atmospheric oxygen. This fundamental distinction enables rockets to achieve much higher altitudes and speeds than turbojets.
What is the difference between jet engines and spaceships?
Jet engines operate by drawing in air, compressing it, mixing it with fuel, and igniting the mixture to produce thrust, relying on atmospheric oxygen for combustion. In contrast, spaceships use rocket engines, which carry both fuel and an oxidizer, allowing them to operate in the vacuum of space where there is no air. This fundamental difference allows jet engines to function within Earth's atmosphere, while rocket engines are designed for the challenges of space travel. Additionally, rocket engines typically generate much higher thrust to escape Earth's gravitational pull.
What type of engine powers a rocket?
Rockets are powered by rocket engines, which operate on the principle of propulsion through the expulsion of high-speed exhaust gases. There are two main types of rocket engines: liquid rocket engines, which burn liquid propellants, and solid rocket engines, which use solid propellants. These engines generate thrust based on Newton's third law of motion, where the expulsion of gas in one direction propels the rocket in the opposite direction. Additionally, some rockets may employ hybrid engines that combine both liquid and solid propellants.
What are two main types of rocket engines?
The two main types of rocket engines are Solid fuel rocket engines and Liquid fuel rocket engines.
Why is it called rocket engine?
A rocket engine is named for its mechanism of propulsion, which involves expelling mass at high speed to generate thrust, based on Newton's third law of motion: for every action, there is an equal and opposite reaction. Unlike traditional engines that rely on atmospheric oxygen, rocket engines carry both fuel and an oxidizer, allowing them to operate in the vacuum of space. This capability is essential for launching spacecraft and achieving high velocities necessary for orbital and interplanetary travel.

What is the difference between thrust and force?
In rocket test bench, how to measure the temperature. Where is the temperature sensor place in rocket test bench.
What can a force do to a rocket that is moving at steay speed?
A force can change the direction of the rocket's motion but not its speed if the force is applied perpendicular to the rocket's velocity. If the force is applied in the same direction as the rocket's motion, it can accelerate or decelerate the rocket.

What is the difference between a rocket and a missile?
A rocket is a vehicle that carries people or cargo into space, while a missile is a weapon designed to be launched at a target.
What is the difference between a rocket and shuttles?
A rocket goes up once and might also come down once, while a shuttle is built to be reuseable.
When does a rocket have a unbalance force?
A rocket experiences an unbalanced force when there is a difference between the thrust produced by the rocket engines and the resistive forces acting on the rocket, such as air resistance or gravity. This unbalanced force causes the rocket to accelerate in the direction of the net force.
