What else can I help you with?
What is the name of the condition when the average velocity of atmospheric molecules around you is not zero?
The condition you are referring to is called temperature. Temperature is a measure of the average kinetic energy of the particles in a substance, such as air. When the average velocity of atmospheric molecules is not zero, it indicates that the substance has a non-zero temperature.
The greatest velocity a falling object reaches?
The greatest velocity that a falling object can achieve is termed, terminal velocity. The equation for terminal velocity is equal to the square root of (2mg / (air density * projected area * drag coefficient))
Acceleration can be defined as the rate at which velocity?
Changes.
A ball is thrown vertically upward. What are its velocity and acceleration when it reaches its maximum altitude What is the acceleration of the ball just before it hits the ground?
At the maximum height the ball will be completely stopped from moving upward or downward; thus the speed of the ball would be 0 mph. The ball is only stopped for a split second and then it begins moving downward, then increasing at 9.81m/s^2 until it reaches maximum velocity.
What does the y - intercept on a force vs acceleration graph represent?
Answer #1:The y intercept should be zero because of Newton's second law. Force andacceleration are directly proportional. The X intercept indicates that there issome force required to overcome friction if friction is not negligible. This valueis the force required to accelerate the object usually very small.===============================Answer #2:It's even easier than that. The graph had better pass through the origin,because zero force on an object means it can't be accelerating, and zeroacceleration of an object means there can't be any net force acting on it.Go back and read Answer #1 above very carefully. It correctly says that they-intercept is zero. But doesn't that mean that the graph must go through theorigin, and that the x-intercept is therefore also zero ? I'm just sayin . . .
Average velocity of a particle is zero but not its average speed .. is it possible?
Yes, it is possible. Average velocity takes into account both the magnitude and direction of motion, and can be zero if the particle moves back and forth. However, average speed only considers the total distance travelled over time, and can be non-zero even if the velocity is constantly changing.
Can a body have nonzero average speed but have zero average velocity give example?
Yes, a body can have a nonzero average speed but zero average velocity if it moves around a closed path and returns to its starting point. For example, if a car travels around a circular track at a constant speed, its average speed will be nonzero (as distance is covered), but its average velocity over the entire trip will be zero as the displacement is zero.
Can the average speed of a body be zero and can the average velocity of a moving body be zero?
Since speed is a scalar quantity, the only way the average speed can be zero is if the instantaneous speed is at all times zero, making it not a moving body, so no on the average speed. The average velocity, on the other hand, can easily be zero. The simplest example is you running in a circle.
Is it possible for an object to move for 10 seconds at a high speed and end up with an average velocity of zero?
Yes, it is possible. If the object moves in opposite directions for half the time at the same high speed, then the displacements cancel out, resulting in an average velocity of zero over the 10 seconds.
Is it possible that a body has zero speed and nonzero velocity?
No because velocity defined as speed in a given direction so if speed is 0 then velocity must also be 0
Can the average velocity of a particle be zero but not its average speed?
Yes, since velocity is speed and direction its average can be zero. For example say a plane flies from point A to point B at 300 mph and turns around to go from B to A at 300 mph; its average velocity is 0 since it is in the same spot as it started ( the velocity vectors cancel) but its average speed is 300 mph.
Is it possible in straight line motion particle have 0 speed and a non-zero velocity .explain?
Sounds like a trick question. The answer is no. Speed is a scalar with magnitude only and velocity is a vector with magnitude (speed) and direction. So If traveling with velocity in a straight line it has speed..
Can particle have zero speed and non zero velocity?
No, a particle cannot have zero speed and non-zero velocity simultaneously. Speed is the magnitude of velocity and if speed is zero, then velocity must also be zero.
Can average speed of a moving object be zerogive an example?
No, it can't. Average VELOCITY can be zero, though.
Is it possible for a body to have average speed but zero average velocity give reason and example?
Yes it is possible. If a body goes round a circular path then distance covered by one full rotation will be 2 pi r But the total displacement is 0. Hence the average speed exists but average velocity does not exist.
Can you have zon zero displacement and a non zero average velocity?
Yes, it is possible to have zero displacement and a non-zero average velocity. This can occur if an object moves back and forth over a certain distance so that the total displacement is zero, but the average velocity is non-zero due to the object covering distance in both directions.
Is it possible in straight line motion a particle have zero and non-zero velocity explain?
Sounds like a trick question. The answer is no. Speed is a scalar with magnitude only and velocity is a vector with magnitude (speed) and direction. So If traveling with velocity in a straight line it has speed..
