What is meant by centripetal acceleration is perpendicular to velocity?

As an object goes round in a circular path, then its velocity will along the tangent at that instant. But centripetal acceleration is normal to that tangent and so along the radius of curvature. As acceleration is perpendicular to the velocity, the direction aspect is ever changing and so the object goes round the circular path.


What is the direction of acceleretion of a body in circular motion?

-- The acceleration is directed from the body to the center of the circle. -- The velocity is tangent to the circle at the place where the body is. That direction is also perpendicular to the acceleration at that moment.


When an object moves in a circular path will the velocity change will there be acceleration?

When an object moves in a circular path, the velocity will change and the there will be acceleration.


Is it possible for an objects velocity to be perpendicular to the objects acceleration?

no


What direction of the velocity causes a circular orbit?

The velocity in a circular orbit changes all the time. The acceleration is towards the center.


Is a person running in a circular track at 7mph an example of constant velocity at zero acceleration and if so why?

No. The velocity and acceleration are not zero because the direction is changing, thus the velocity and acceleration is changing.


When are velocity and acceleration perpendicular to each other?

When body is moving in a circle.


Is an object going in circles at a constant speed an accelerated motion?

Yes. Acceleration is the change in velocity, and velocity is a vector, which means it has direction. Because an object undergoing uniform circular motion is changing direction, it is changing velocity, and thus, accelerating.


How do you draw velocity and acceleration diagrams?

Velocity diagrams are drawn perpendicular to the link ....whereas acceleration diagrams are drawn by knowing the values 2 components radial or centripetal component and tangential component.......the radial component moves parallel to the link and perpendicular to the velocity diagram.....but the tangential component moves perpendicular to the link and parallel to the velocity diagram .


In order for an object to move in uniform circular motion it must be accelerating?

Yes as a body moves along a circular path with uniform speed, its direction is ever changing. Hence the velocity is changing. So acceleration must be present. If acceleration vector is in the direction of the velocity then definitely its magnitude would change and so we cannot say the motion to be uniform. So the acceleration has to be perpendicular to the velocity vector, so it has to be along the radius. Hence the acceleration is named as radial acceleration. The force thus produced is known as centripetal force ie centre seeking force.


Why is an object traveling in a circular motion?

acceleration is change in velocity.. and velocity constantly changes in circular motion, as the direction constantly changes. This constant change in velocity causes the object to accelerate.


What is the shape of the orbit when the velocity of the satellite is everywhere perpendicular to the force of gravity?

If the velocity of the satellite is always perpendicular to the force of gravity, then the eccentricity of the orbit is zero, and it's perfectly circular.
