Why can velocity and acceleration never be parallel?
As a projectile moves in its path, the velocity and acceleration vectors are perpendicular to each other at its highest point. the vectors of the velocity and acceleration will never be parallel unless the objects path is going straight up or straight down.
How are velocity and acceleration are related?
Acceleration is the rate of change of velocity. If an object is changing its velocity, i.e. changing its speed or changing its direction, then it is said to be accelerating. Acceleration = Velocity / Time (Acceleration)
Are acceleration and velocity parallel in uniform circular motion?
In a uniform circular motion, A. the acceleration and the velocity are always parallel. the direction between the velocity and the acceleration will vary as the object moves around the circle.
Are velocity and acceleration perpendicular?
Since acceleration is directly proportional to force, so acceleration is also along y-axis. This means that velocity & acceleration are perpendicular to each other.
In which of the following cases are its acceleration and velocity vectors parallel?
Answer is b. In straight-line motion where the object accelerates, the acceleration is parallel to the velocity.
What is the phase relationship between velocity and acceleration in simple harmonic motion?
Answer Expert Verified. So velocity is π/2 radians ahead of displacement in the phase angle. So acceleration is π radians ahead of displacement and π/2 rad ahead of velocity.
What are displacement velocity and acceleration and what are their relationships to each other in terms of motion?
Displacement is a vector which points from the initial position of an object to its final position. The standard units of displacement are meters. Velocity is a vector which shows the direction and rate of motion. Acceleration is a vector which shows the direction and magnitude of changes in velocity.
What happens to speed velocity and acceleration when an object moves in a circle with uniform speed?
The object moves with uniform speed in a circle which means the direction of velocity changes constantly. Velocity has both magnitude and direction. Whereas, in case of acceleration, moving in a circle does not change the acceleration. The magnitude and direction is constant for acceleration.
Is acceleration always parallel to velocity?
No. Acceleration that is perpendicular to velocity changes ONLY the velocity’s direction. The speed remains unchanged, only the direction of velocity.
Are the velocity and acceleration vectors anti-parallel?
As David Vogel answered, the velocity and acceleration vectors aren’t necessarily anti-parallel, but can be. The direction of the velocity vector is in the direction of the object’s motion. The direction of the acceleration vector is in the direction of the net force on the object. Toss a ball straight up.
What happens to velocity when acceleration is parallel to acceleration?
Answer Wiki. When acceleration is such that it changes only magnitude of velocity and not the direction of velocity, then velocity will remain parallel to the acceleration.
What is the relationship between acceleration and motion?
It is concerned with how the body’s motion is changing with respect to time. The change in object’s speed and direction are indicated by the component of acceleration, i.e. direction. When the direction of acceleration is parallel to velocity, then it is believed that object is accelerating or its speed is going up.
Why is straight line motion required for acceleration to increase?
Straight line motion is required to keep the acceleration in the same direction as the velocity (parallel or anti-parallel). If the velocity and acceleration are in the SAME direction then the speed will be increasing (in the positive or negative direction).
