No, it can't. Average VELOCITY can be zero, though.
Yes; for example, an object moving in a circle.
A negative average velocity indicates that an object is moving in the opposite direction of the chosen positive direction. For example, a negative average velocity would mean the object is moving left if the positive direction is considered right.
Yes, average speed can be used to calculate the speed of an object moving at a constant speed. This is because the average speed over a whole journey for an object moving at a constant speed is the same as its actual speed.
Yes, an average speed of a moving object can be zero if the object returns to its starting position within the same amount of time it takes to move away from it. For example, if a car travels 10 miles away from its starting point and then travels back 10 miles in the same amount of time, its average speed can be zero.
An object at rest. Actually that's the only possible example for a single object. For two objects, you can have objects moving in opposite directions; for example, one may have a momentum of +100 units, and the other, a momentum of -100 units.
Distance traveled divided by the time it took.
average speed
The average speed of an object moving in a specific direction is calculated by finding the mean of the magnitude of its velocities in various directions. This involves taking into account both the speed and the direction of the object's motion to determine an overall average.
an object moving through a vaccuum
An object can move in a circle at different speeds.
The average speed of an moving object is determined by using the formula velocity=distance/time or v=d/t.
An example of a force acting on an object but the object isn't moving is when you push against a wall. The force you apply with your hands is countered by an equal and opposite force from the wall, resulting in the object (the wall) not moving.
