An object experiences a net zero external unbalanced force is it possible for the object to be travelling with a non-zero velocity?
Yes, it is possible for an object to be traveling with a non-zero velocity even if it is experiencing a net zero external unbalanced force. This is because the object may have inertia, which allows it to maintain its current velocity unless acted upon by an external force.
Why are rockets launched as close to the equator as possible?
Rockets are launched as close to the equator as possible to launch satellites most economically by taking full advantage of the Earth's rotational velocity, which is about 1000 miles per hour at the equator and slower at all higher latitudes. This is 1000 miles per hour less speed that the rocket needs to provide and a significant savings in rocket fuel. However, other rockets are not launched from the equator as there is no similar advantage (e.g. rockets launching polar orbiting satellites or military warheads can be launched from anyplace and going to the equator to launch them would be an unnecessary expense with many disadvantages).
Compared to the velocity of radio waves the velocity of visible light waves is?
The velocity of visible light waves is the same as the velocity of radio waves in a vacuum, both traveling at the speed of light (approximately 299,792 kilometers per second).
Is your speed is constant if you are traveling in a straight line with an acceleration of zero?
If your acceleration is zero, then yes, you are traveling at a constant speed. The path does not matter. Acceleration measures the change in velocity, so an acceleration of zero means that there is zero change in velocity and therefore the speed is constant.
Is it possible of a body to have its velocity and acceleration pointing in opposite direction plot a velocity-time graph if yes?
Yes, it is possible for a body's velocity and acceleration to be in opposite directions. This would result in the body's velocity decreasing over time while its acceleration remains negative. On a velocity-time graph, this situation would be represented by a curve that starts with a positive velocity and decreases over time.
Why doesn't spacecrafts not slow down during the journey?
In space, there is no air resistance to slow down spacecraft traveling at constant velocity. Additionally, spacecraft can use thrusters or gravitational assists to adjust their speed if needed. The laws of physics allow spacecraft to maintain their speed in the vacuum of space.
Two rockets are traveling at exactly the same speedhow is it possible that one rocket can be traveling at an orbital velocity while the other rocket is traveling at an escape velocity?
the rocket is just gonna explode in clear view like the bumuda triangle leaves no marks of the murders
When traveling at a constant velocity the acceleration is?
When traveling at a constant velocity, the acceleration is zero. This is because acceleration measures the rate of change of velocity, and if velocity is not changing, there is no acceleration.
Is a projectile velocity the highest velocity that can be reached?
No, a projectile velocity is the initial velocity at which a projectile is launched. The highest velocity a projectile can reach depends on factors such as air resistance, gravity, and propulsion force. In some cases, the velocity of a projectile can increase or decrease after it is launched.
Can an object traveling at constant velocity have acceleration?
No, if an object is traveling at a constant velocity, it means that its speed and direction are not changing. Acceleration is the rate at which velocity changes over time, so an object with constant velocity by definition cannot have acceleration.
What happens to a spacecraft that is launched at a speed less than 8000 meters per second?
If a spacecraft is launched at a speed less than 8000 meters per second, it may not have enough velocity to escape Earth's gravitational pull and enter orbit around the planet. Instead, it may re-enter the Earth's atmosphere and burn up due to friction with the air.
Is there an acceleration when an object traveling at constant velocity and why?
No, there is no acceleration when an object is traveling at a constant velocity. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change and therefore no acceleration.
When a ball is traveling at a constant velocity of 50 ms and has been traveling for over 2 minutes what is the balls acceleration?
If the ball is traveling at a constant velocity of 50 m/s, then its acceleration is 0 m/s^2. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity, and therefore no acceleration.
Compare velocity from acceleration?
Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)
What is the velocity of an object traveling at 42448409 m/s?
The velocity of an object traveling at 42,448,409 m/s is 42.45 km/s.
How do spacecraft take off from earth?
They need to reach escape velocity (about seven miles per second) to break away from Earth's gravity. (Anything traveling more slowly will eventually fall back to Earth.)
How is the speed of a spacecraft measured?
The speed of a spacecraft can be measured by tracking its position over time using instruments such as radar or GPS. The velocity of the spacecraft can then be calculated by determining the rate at which its position is changing. Additionally, spacecraft may use onboard sensors like accelerometers to measure speed and acceleration.
