Simply, yes. I'm assuming we're talking hypothetically, otherwise it would be very dificult to measure.
Depending on the starting velocity and the amount of time the object has been moving, there is no reason why at some point the velocity and acceleration cannot have equal magnitudes.
Example 1:
An object is moving at a fixed velocity of 9.8ms. At time t, a force is applied to it to create an acceleration of 9.8m/s^2) (in any direction). Now at the instant t, before it has had a chance to change velocity, both requirements are met.
Example 2, more simply:
The velocity 9.8ms much have been given because it is approximately equal to the acceleration due to gravity near the earth. If an object is dropped near to the earth's surface, assuming no air resistance, it will start at 0ms (not moving) and accelerate at 9.8m/s^2, ie for every second it is accelerating, it will speed up by 9.8m/s. Therefore, after 1 second, it will be travelling at exactly 9.8m/s.
For going in the opposite direction, think about what happens when you throw a ball upwards, where the aceleration due to gravity is downwards.
Be careful with your units. ms usually signifies metres x seconds, whereas velocity is metres per second, or metres divided by seconds, m/s or ms^-1
Same as acceleration - just remember that "deceleration" is an acceleration in a direction opposite to the direction of movement.Same as acceleration - just remember that "deceleration" is an acceleration in a direction opposite to the direction of movement.Same as acceleration - just remember that "deceleration" is an acceleration in a direction opposite to the direction of movement.Same as acceleration - just remember that "deceleration" is an acceleration in a direction opposite to the direction of movement.
yes, if the acceleration is in the opposite direction of the velocity.
Anytime an object is slowing down, its acceleration is in the opposite direction to its velocity.
In the opposite direction to the course of acceleration.
Take the velocity to be in positive direction. Positive acceleration increases velocity and they are in the same direction. Negative acceleration reduce velocity and they are in opposite direction. It does not matter if the motion in linear or anfular.
The acceleration is opposite the direction the object is moving, so the acceleration is negative and southward.
The opposite direction. To stop a moving object requires an acceleration in the direction opposite its motion.
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
Yes, velocity and acceleration can point in the opposite direction to each other. This is because neither one depends on the other. When velocity and acceleration are opposite each other this results in slowing down, for example when you hit the break on your car.
Positive acceleration = speeding up; speed increasing in the direction you're moving.Negative acceleration = slowing down; speed decreasing in the direction you're moving,or speed increasing in the opposite direction.
It accelerates in the opposite direction. Its velocity increases in the opposite direction to the direction that has been assigned positive.
It accelerates in the opposite direction. Its velocity increases in the opposite direction to the direction that has been assigned positive.
