β 13y agoIf an object's velocity-time graph is a straight line parallel to the time axis, then the object's acceleration is zero. This means that the object is moving at a constant velocity.
Velocity is parallel to acceleration when an object is moving with constant speed in a straight line, as the direction of the velocity and acceleration vectors are aligned. This means that the object's speed may be constant, but its direction can change.
The velocity and acceleration of a body are parallel when the body is moving along a straight path with a constant speed. In this case, the velocity is constant, and since acceleration is the rate of change of velocity, it is zero. Therefore, both the velocity and acceleration vectors are parallel and pointing in the same direction.
If the velocity-time graph is a straight line parallel to the time axis, it means the velocity is constant. The acceleration would be 0 because there is no change in velocity over time.
The problem is that a so-called "velocity-time" graph is really a "speed-time" graph.A complete description of "velocity" at any point in time includes speed and direction,but the graph can only show speed, that is, the magnitudeof velocity, vs. time, butit can't show the direction of the motion. If the direction changes with time, thenthat constitutes acceleration, but we can't discern it from the graph.If the "v-t" graph is a straight line parallel to the time axis, then we know the speed,and therefore the magnitude of velocity, is not changing. If we also know from someother source that the motion is in a straight line, then we may say that the accelerationis zero. But if we have no other information in addition to the graph, we can't reach afull conclusion regarding the acceleration.
Yes, at the highest point of the projectile's path, the velocity and acceleration vectors are perpendicular to each other. This is because at the peak of its trajectory, the velocity is momentarily zero and only the acceleration due to gravity is acting on the projectile.

when velocity of a car is increasing then velocity and acceleration are parallel to each other.

Acceleration = Final velocity - Initial velocity / time

Yes, at the highest point of the projectile's trajectory, the velocity and acceleration vectors are parallel to each other. This is because the velocity is momentarily zero, and the acceleration due to gravity is acting vertically downward, pointing in the same direction as the velocity.
The acceleration of an object moving in a straight line at a constant speed is zero. Acceleration is the rate of change of velocity, so if the speed is constant, there is no change in velocity and thus no acceleration.
momentum is product of moment of inertia and angular velocity. There is always a 90 degree phase difference between velocity and acceleration vector in circular motion therefore angular momentum and acceleration can never be parallel
The formula to determine acceleration in a straight line is: acceleration = change in velocity / time taken for the change. This can be expressed as a = (vf - vi) / t, where a is the acceleration, vf is the final velocity, vi is the initial velocity, and t is the time taken for the change.
Yes, if an object is moving in a straight line and has no change in its speed or direction, then it has no acceleration. Acceleration is the rate of change of velocity, so if the velocity is constant, the acceleration is zero.
