What is the difference between projectitle motion and a rocket motion?
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 a measure of?
angular momentum is the measure of angular motion in a body.
Is angular momentum always parallel to angular acceleration?
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
Use of angular momentum in your daily life?
Angular momentum is evident in various aspects of daily life, such as when riding a bike or spinning on a swivel chair. When a cyclist turns, their body leans into the turn, utilizing angular momentum to maintain balance and control. Similarly, when a figure skater pulls in their arms while spinning, they increase their rotation speed due to the conservation of angular momentum. These principles help us understand motion and balance in everyday activities.
What is called operator which commutes with hamiltonian?
An operator that commutes with the Hamiltonian is called a conserved quantity or a constant of motion. When an operator ( A ) satisfies the commutation relation ([A, H] = 0), where ( H ) is the Hamiltonian, it indicates that the observable associated with ( A ) is conserved over time in a quantum system. This means that the expectation value of the observable does not change as the system evolves. Examples include total momentum and total angular momentum in isolated systems.
With out air pressure at what point or points in its path does a projectile have its minimum speed and its maximum?
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
What are some common projectile motion problems with solutions and answers?
Common projectile motion problems involve calculating the trajectory of an object launched into the air at an angle. These problems typically require finding the initial velocity, angle of launch, time of flight, maximum height, and range of the projectile. Solutions involve breaking down the motion into horizontal and vertical components, using kinematic equations, and applying principles of physics such as conservation of energy and momentum. Answers are usually numerical values that represent the specific characteristics of the projectile's motion.
What are some common strategies for solving projectile motion problems?
Common strategies for solving projectile motion problems include breaking down the motion into horizontal and vertical components, using kinematic equations to calculate initial velocity, time of flight, and maximum height, and considering factors such as air resistance and launch angle. Additionally, utilizing trigonometry to determine the angle of launch and applying the principles of conservation of energy and momentum can help in solving projectile motion problems effectively.
What is the proof that 45 degrees provides the maximum range for projectile motion?
The proof that 45 degrees provides the maximum range for projectile motion is based on the fact that at this angle, the horizontal and vertical components of the initial velocity are equal. This results in the projectile traveling the farthest distance before hitting the ground.
How can one determine the maximum height reached in projectile motion?
To determine the maximum height reached in projectile motion, you can use the formula: textMaximum height left(fracv02 sin2(theta)2gright) where ( v0 ) is the initial velocity, ( theta ) is the launch angle, and ( g ) is the acceleration due to gravity. By plugging in these values, you can calculate the maximum height the projectile reaches.
What is the maximum angle needed to have a longest range in projectile motion?
45 degrees is the furthest one
How does air resistance affect the components of projectile motion?
Air resistance acts as a resistive force that opposes the motion of the projectile. It causes the projectile to experience a decrease in speed and alters its trajectory, leading to shorter horizontal distances and lower maximum heights compared to ideal projectile motion in a vacuum. Additionally, air resistance can cause the projectile to fall at a steeper angle compared to when it is neglected.
How do you find projectile motion?
Projectile motion is a form of motion in which a projectile is thrown near the earth's surface. When thrown, the projectile moves along a curved path because of gravity. An example of projectile motion is a sprinkler shooting water into the air and the water falling back down to Earth.
What are some common projectile motion problems and what are the solutions to these problems?
Common projectile motion problems include determining the maximum height reached by an object, the time of flight, the range of the projectile, and the velocity at a certain point. Solutions to these problems involve breaking down the motion into horizontal and vertical components, using kinematic equations to calculate the necessary parameters, and applying the principles of projectile motion such as the independence of horizontal and vertical motion.
What are some common projectile problems encountered in physics?
Common projectile problems encountered in physics include calculating the initial velocity, angle of launch, maximum height, range, time of flight, and impact velocity of a projectile. These problems often involve using equations of motion and principles of projectile motion to analyze the motion of an object launched into the air.
What are some common projectile problems in physics and how can they be solved?

How does the gravity affect the two components of projectile motion?
Projectile motion has two components horizontal motion and vertical motion. Gravity affects only the vertical motion of projectile motion.
