Why is the acceleration of a body moving uniformly in a circle directed towards the centre?
The acceleration of a body moving uniformly in a circle is directed towards the center of the circle because it is constantly changing direction due to the change in velocity (even though the speed is constant). This change in direction results in a centripetal acceleration that keeps the body moving in a circular path.

Why is acceleration of a body moving uniformaly in a circle directed toward the centre?
The acceleration of a body moving uniformly in a circle is directed towards the center because the velocity of the body is constantly changing direction, even though its speed remains constant. This change in direction of the velocity results in a centripetal acceleration that is required to keep the body moving in a circular path.
What is the direction of acceleration in circular uniform motion?
The direction of acceleration in circular uniform motion is directed towards the center of the circle, which is also known as centripetal acceleration. This acceleration is responsible for keeping an object moving in a circular path instead of moving in a straight line.
Why Centripetal acceleration always directed toward the centre of circle?
Centripetal acceleration is directed towards the center of the circle because it is the force that keeps an object moving in a circular path. Given that an object moving in a circular path is constantly changing its direction, the centripetal acceleration is necessary to ensure that the object remains on the curved path rather than moving in a straight line.
How will a ray directed towards the centre of curvature of a convex mirror be reflected?
A ray directed towards the centre of curvature of a convex mirror will reflect back on itself along the same path. This is because the centre of curvature is located on the normal line, so the angle of incidence and the angle of reflection will be equal due to the principle of reflection.
Why does acceleration due to gravity always point vertical downward?
Acceleration due to gravity is due to the force of gravitation exerted on a body by the earth. All bodies get attracted towards the centre of the earth. So the acceleration is always pointed vertically downwards.

Why Centripetal acceleration always directed toward the centre of circle?
Centripetal acceleration is directed towards the center of the circle because it is the force that keeps an object moving in a circular path. Given that an object moving in a circular path is constantly changing its direction, the centripetal acceleration is necessary to ensure that the object remains on the curved path rather than moving in a straight line.
What is the direction of acceleration when moving in a circle?
The direction of acceleration when moving in a circle is toward the center of the circle. This centripetal acceleration is responsible for changing the direction of the velocity vector as an object moves in circular motion.
Can a car move around a circular racetrack so that the car has a tangential acceleration but no centripetal acceleration?
No, If a car moves around a circular race track with any constant speed, the acceleration is directed towards the centre. So it has a centripetal acceleration. The tangential acceleration would be irrelevant unless the car has an instantaneous tangential velocity of zero. Then the centripetal acceleration is zero. However, this would only exist for that small instant in time.
What is acceleration toward the center of a circle caused by?
The force which causes acceleration towards the centre of a circle is called Centripetal force but what causes it can vary.
What is the direction of acceleration due to gravity State with reason?
The acceleration between two bodies is always towards the centre of mass of the bodies in question.
How will a ray directed towards the centre of curvature of a convex mirror be reflected?
A ray directed towards the centre of curvature of a convex mirror will reflect back on itself along the same path. This is because the centre of curvature is located on the normal line, so the angle of incidence and the angle of reflection will be equal due to the principle of reflection.

Acceleration due to gravity is due to the force of gravitation exerted on a body by the earth. All bodies get attracted towards the centre of the earth. So the acceleration is always pointed vertically downwards.
Which direction does the centripetal acceleration point?
Centripetal acceleration is acceleration towards the center of the movement.
Explain why when a ball is dropped from a height its speed increases?
The ball experiences the force of gravity which pulls it towards the centre [of mass] of the earth. According to the essence of the second of Newton's Laws of Motion, a force acting on a body accelerates it in the direction of the force. Thus, the ball speed up towards the centre of the earth.Whenever there is a force - in this case gravity - there will be an acceleration. (To be precise, a NET FORCE is required to provide acceleration.) According to Newton's Second Law, the acceleration is equal to the force divided by the mass.
Does the acceleration of a body moving in circular path remain constant?
If the speed of the object doesn't change, then yes.
