Why does the rocket have to go sideways?
The rocket needs to go sideways to reach orbit. By moving sideways fast enough, the rocket can overcome the force of gravity pulling it back towards Earth. This sideways velocity allows the rocket to enter a stable orbit around Earth.
If a rocket in space burns fuel consumes energy at a constant rate its velocity should increase at a constant rate ignoring the loss of mass so why is kinetic energy a function of V SQUARED?
Assuming constant acceleration, at a higher speed, the force must be applied over a larger distance to get the same change in speed. Since work = force x distance, it requires more work to get the same change in speed, once the rocket has a higher speed.In the case of the rocket, the situation is not as simple as you put it. For example, all the fuel the rocket required to change the rocket's speed, say, from 1000 m/s to 1100 m/s, must be accelerated first, using more fuel at first. Also, the exhaust gases from the rocket have kinetic energy, which depend on the rocket's current speed - when it is just starting, the exhaust gases have a higher speed, and therefore more kinetic energy. To see whether energy is conserved or not, this kinetic energy would have to be included in your calculations.
A rocket ship leaves earth's atmosphere its initial velocity is less than its final velocity which is this an example of?
This is an example of acceleration. Acceleration is the rate at which an object changes its velocity, either by speeding up or slowing down. In this case, the rocket ship is speeding up as it leaves Earth's atmosphere, with its final velocity being greater than its initial velocity.
What speed do rockets break earths gravitational pull?
Enough to support their own weight, plus a little more for motion. It is possible, in theory, to imagine a rocket moving away from the Earth at a slow walking pace. In real life you don't do that, you get away from Earth's pull as quickly as you can manage to do so.
When does a landing rocket reach terminal velocity?
It may unless it has an attached parachute
How can a rocket in space shut off its engines and still keep moving?
A rocket in space can shut off its engines and still keep moving due to the principle of inertia. Once the engines are turned off, the rocket will continue to move forward at a constant velocity unless acted upon by another force, such as gravity or a change in trajectory.
What is meant by the critical velocity of a ball moving in a vertical circle?
The critical velocity of a ball moving in a vertical circle is the minimum velocity required at the top of the circle to prevent the ball from losing contact with the track. Below the critical velocity, the ball will fall off the track at the top of the circle.
A rocket of initial mass m0 is shot vertically upward Assume that the motion occurs under constant gravitational acceleration g Let the initial velocity of the rocket on the surface of the earth be?
the initial velocity of the rocket is zero.
How will momentum and velocity affect the launch of a rocket?
Momentum is the product of an object's mass and velocity, so a rocket with high momentum will have more force upon launch. Velocity is the speed at which the rocket is moving, which affects how quickly it accelerates and gains height. Both momentum and velocity are crucial for determining the rocket's trajectory and performance during launch.
A space probe may be carried by a rocket into outer space what keep the probe moving after the rocket no longer pushes it?
Once the rocket stops pushing the probe, it continues moving due to its inertia. In the vacuum of space, without any air resistance to slow it down, the probe will keep moving at a constant velocity until acted upon by another force, such as gravity from a celestial body or a thruster on the probe itself.
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.
Can a body posses velocity when its accleration is zero?
Of course. You need to go back and review the definitions of those terms. Acceleration is the rate at which velocity changes. If velocity is not changing, then there is no acceleration. But the velocity doesn't have to be zero just because it's not changing. Velocity is the speed of an object and the direction in which it's moving. If it's moving at a constant speed in a straight line, then it has plenty of velocity. But since the speed isn't changing and the direction isn't changing, there's no acceleration. If acceleration comes along somehow ... such as by igniting a rocket motor, or gravity pulling the object downward, or someone reaching out and giving the object a push, then the speed or direction may change, and that'll be a change of velocity.
When does a rocket have balance force?
A rocket has balanced forces when the thrust from the engines pushing it forward is equal to the drag and gravity pulling it back. This balance allows the rocket to maintain a constant velocity or stay in a stable orbit.
What will happen if the moving gases of a rocket have a greater mass and speed?
If the moving gases of a rocket have a greater mass and speed, the rocket will experience increased thrust, resulting in higher acceleration and velocity. This leads to improved performance and efficiency in terms of reaching its intended destination in space.
Would a rocket travel at a constant speed?
Assuming its engines are off, it would travel at a constant speed ONLY if there is no force of gravity that changes its velocity. In practice, there are always forces that will change its velocity, at least in the long term.
What you think the rocket kinetic energy is right after takeoff?
The rocket's kinetic energy right after takeoff is at its maximum as it is moving at its highest velocity at that point. The kinetic energy of the rocket is a measure of the energy it possesses due to its motion.
Why is it not a good idea to assume that the mass is constant in a bottle rocket?
Assuming that mass is constant in a bottle rocket is not ideal because as the rocket fuel is burned and expelled, the mass of the rocket decreases, leading to changes in its acceleration and velocity. This can impact the accuracy of predictions related to the rocket's trajectory and performance. Taking into account the changing mass allows for more precise calculations and design considerations.
