When is velocity parallel to acceleration?
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.
Explain the circumstances in which the velocity and acceleration of the body is parallel?
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.
What would be the acceleration of a body if its velocity time graph is a line parallel to the time axis?
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.
What is the value of acceleration if v-t graph is a straight line parallel to the time axis?
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.
Is there any point along the path of projectile where velocity and acceleration vectors are parallel to each other?
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.
When is velocity parallel to acceleration?
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.

Explain the circumstances when the acceleration and the velocity of car are parallel?
when velocity of a car is increasing then velocity and acceleration are parallel to each other.
What formula do you use to calculate the acceleration of an object moving in a straight line?
Acceleration = Final velocity - Initial velocity / time

What is the acceleration of an object that travels in a straight line at a constant speed?
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.
Is there any point along the path of projectile where velocity and acceleration vectors are perpendicular to each other?
Using the term "trajectory" implies that the acceleration you are concerned about is due to gravity. Gravity will always be perpendicular to the surface. Unless the trajectory begins perpendicular to the surface, it will never change to become perpendicular and the velocity will never be in a direction parallel to the acceleration. If it starts perpendicular to the surface it will start and remain perpendicular. Of course if you have another force acting on the object - such as wind - the component of the velocity vector parallel to the ground could be reduced to zero and at that point the only remaining component of the velocity vector would be that perpendicular to the ground and parallel to the acceleration. Likewise if the object is being propelled by an engine or rocket, the trajectory could be parallel to the force any time the acceleration vector became parallel to the velocity vector.
What is the horizontal acceleration formula used to calculate the rate of change in velocity over time in a straight line motion?
The horizontal acceleration formula used to calculate the rate of change in velocity over time in straight line motion is: Acceleration (Change in Velocity) / Time
Is angular momentum always parallel to angular 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
What is the formula you use to determine the acceleration of an object moving in a straight line?
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.
