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 else can I help you with?
What is meant by the term acceleration?
Acceleration refers to the rate at which an object's velocity changes over time. It can be an increase or decrease in speed, or a change in direction. The formula for acceleration is acceleration = (final velocity - initial velocity) / time.
What is the slope of centripetal force vs velocity squared?
The slope of centripetal force vs velocity squared graph represents the mass of the object undergoing circular motion. This relationship is described by the equation Fc = mv^2 / r, where Fc is the centripetal force, m is the mass of the object, v is the velocity, and r is the radius of the circular path. Therefore, the slope would be equal to the mass of the object.
What is meant by an acceleration of -2 ms2?
An acceleration of -2 m/s^2 means that the velocity of an object is decreasing by 2 meters per second every second. The negative sign indicates that the acceleration is in the opposite direction of the velocity.
What is meant by positive acceleration and negative acceleration?
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.
Can an object have constant velocity and non-zero acceleration?
No, an object cannot have constant velocity and non-zero acceleration simultaneously. If an object has non-zero acceleration, it means its velocity is changing over time. Constant velocity implies a steady speed in a straight line with no change in direction or magnitude.
What is meant by the term acceleration?
Acceleration refers to the rate at which an object's velocity changes over time. It can be an increase or decrease in speed, or a change in direction. The formula for acceleration is acceleration = (final velocity - initial velocity) / time.
What is meant by the acceleration of a body?
the rate of change in the velocity of a body
What is meant by inifinite acceleration?
The answer becomes clear with the aid of some simple mathematics. Acceleration is defined as (change in velocity)/(time for the change) . Clearly, then, acceleration is infinite whenever velocity changes in "no time".
What is meant by an acceleration of -2 ms2?
An acceleration of -2 m/s^2 means that the velocity of an object is decreasing by 2 meters per second every second. The negative sign indicates that the acceleration is in the opposite direction of the velocity.

How do you find distance with uniform velocity time final velocity and initial velocity?
If the velocity is uniform, then the final velocity and the initial velocity are the same. Perhaps you meant to say uniform acceleration. In any event, the question needs to be stated more precisely.
Can an object have constant velocity and non-zero acceleration?
No, an object cannot have constant velocity and non-zero acceleration simultaneously. If an object has non-zero acceleration, it means its velocity is changing over time. Constant velocity implies a steady speed in a straight line with no change in direction or magnitude.
How do you recognize acceleration graphs?
Acceleration graphs show changes in velocity over time. A positive slope indicates speeding up, a negative slope indicates slowing down, and a horizontal line indicates constant velocity. The steeper the slope, the greater the acceleration.
When is meant by accleration due to gravity?
Dropping a stone from a tall building is an example of acceleration due to gravity. The stone's speed will increase as it falls until it reaches terminal velocity.
What is meant by tangential speed?
Tangential speed refers to the speed of an object as it moves along a curved path. It is the speed of an object in the direction tangent to the curve at any given point. This speed is perpendicular to the centripetal force that keeps the object moving in a circular path.
What is meant by the critical velocity of a ball moving in a vertical circle?
The critical velocity of a ball moving in a vertical circle is the minimum velocity required at the top of the circle to prevent the ball from losing contact with the track. Below the critical velocity, the ball will fall off the track at the top of the circle.
