What will happen to the speed of a space ship if it turns off its engines in space?
First of all, remember that it takes force to change the speed or direction of amoving object, but not to keep it moving at a constant speed in a straight line.Whatever the space ship's speed and direction are when the engine is switched off,it continues moving at that same speed and in that same direction, until some forcecomes along to change them. That force might be, for example, a gravitational one,if the space ship's motion brings it close enough to a planet, a moon, or an asteroid.
Why is fuel needed to change the speed or directions of a probe in space?
A moving object will continue moving in the same direction and at the same speed unless some force acts upon it. The only effective way to do this with a spacecraft is to eject mass away from it. By using combustible fuel we can eject mass at a high speed, which larger velocity changes than ejecting material at a low speed.
If the shuttle travels 17500 mph why does it look like they are not moving in space walks?
Because everything (the Shuttle, the camera the astronaut) is traveling at the same speed. If you are in an airplane you and your fellow passengers are traveling at several hundred MPH but to you it looks like the things around you are standing still. Another example is as the Earth rotates, you and the surface you are standing on is moving at about 1000 MPH, but to you is looks like you're still.
How fast is the Andromeda galaxy coming at the Milky Way?
There is a new substantiated hypothesis that the universe is now expanding and contracting at the same time (here we go: nasha-vselennaia.ru/?p=10056) . We think that some galaxies are moving away from us and some are approaching. The Andromeda is approaching to us with high speed (almost with the speed of light), but it falls into the black hole, at the center of which is our galaxy, the Milky Way. Because of the great gravitational force between our galaxy and Andromeda, there is gravitational compression of time around us. That is, the time passes slowly around us, and it seems to us that Andromeda is approaching us slowly. The closer it comes to us, the more will be the gravitational force and the time will slow down. We would think that the Andromeda is braking, slowing its approach, but it is actually approaching us almost at the speed of light. We have nothing to be afraid of. According to our time, it needs billions of years to collide with our galaxy. If we really live in four-dimensional space, there is nothing surprising.
Is the space station moving or stationary?
Its moving. Quickly. It is in orbit around the earth, the same as any satellite.
Can two cars moving with the same velocity collide?
Yes, two cars moving with the same velocity can collide if their paths intersect or if one fails to stop in time to avoid hitting the other. Velocity only describes the speed and direction of an object's motion, not its position. So, the cars can still collide if they have the same velocity.
Can two moving cars of different mass have the same kinetic energy?
Yes, two moving cars of different mass can have the same kinetic energy if they are moving at the same speed. Kinetic energy depends on both mass and velocity, so as long as the cars are moving with the same speed, their kinetic energies will be equal regardless of their masses.
If two toy cars of the same mass are moving from the opposite directions will they collide at a half way point and what will happen after the collision?
Yes, if two toy cars of the same mass are moving towards each other, they will collide at the halfway point. After the collision, their velocities will change according to the principles of conservation of momentum and kinetic energy. The cars will bounce off each other in opposite directions, with the total momentum remaining the same before and after the collision.
Why cars faster than bikes at same speed?
Huh? If they are both moving at the same speed neither is faster.
Two cars moving in opposite directions with same mass and speed and in what direction and what speed does the wreckage move?
If they collide head on, the wreckage will remain at the point of impact (real world considerations aside).
Can one car be in front of the other when both cars moving at the same speed heading to the same direction?
Of course.
What must be necessary for two cars to have the same momentum while moving along the interstate?
The product of the car's mass and its speed must be the same for both cars.
How is crash speed determined when two vehicles are moving in the same direction?
The difference between the two speeds. So if one car is traveling at 60mph and the other is 70mph, it would be a 10mph difference since they are traveling in the same direction. Now, if they were colliding head on, it would be 130mph total speed.Also, 2 cars traveling at exactly the same speed and direction (assuming they start a certain distance apart) will never collide and will maintain that exact distance they started apart.
Can two cars of different mass have the same kinetic energy?
Yes, two cars of different mass can have the same kinetic energy if they are moving at the same speed. Kinetic energy is dependent on both mass and speed, so if the speeds are equal, the kinetic energy will be the same regardless of the mass.
What is the impact speed when a car moving at 100 kmh bumps into the rear of another car traveling in the same direction at 98 kmh?
The impact speed when the car moving at 100 km/h bumps into the rear of another car traveling at 98 km/h is 2 km/h. This is because the difference in speeds between the two cars is 2 km/h when they collide.
Two cars are traveling along the same road The same speed but at different velocities how?
If two cars are traveling at the same speed but different velocities, it means they are heading in different directions or experiencing different accelerations. Velocity is a vector quantity that includes both the speed and the direction of an object's motion, so if two objects are moving at the same speed but in different directions, they have different velocities.
What is the word for not moving or moving at a constant speed in the same direction?
The word is "stationary" for not moving, and "constant velocity" for moving at a constant speed in the same direction.
