When an object moving in a certain direction with an acceleration in the perpendicular direction?
(c) An object moving in a certain direction with acceleration in the perpendicular direction. Consider the circular motion of an object. When the object is moving along a circular motion its path is along the tangent. The direction of the body is always perpendicular to its acceleration.
What is the direction of acceleration of an object is moving to the right and slowing down?
In each case, the acceleration of the object is in the negative direction. In Example C, the object is moving in the positive direction (i.e., has a positive velocity) and is slowing down. According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity.
Which of the following scenarios the acceleration acting on the object will be perpendicular to the velocity?
(c) an object moving in a certain direction with an acceleration in the perpendicular direction. Answer : (a) It is possible; an object thrown up into the air has a constant acceleration due to gravity acting on it. However, when it reaches its maximum height, its velocity is zero.
Why is an object traveling in a circular motion accelerating?
The velocity vector is constant in magnitude but changing in direction. For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the velocity vector is changing.
How is the direction of the acceleration vector related to the direction of the change in velocity vector explain?
Accelerating objects are changing their velocity – either the magnitude or the direction of the velocity. Objects moving in a circle at a constant speed are accelerating due to their changing direction. The direction of the acceleration is directed toward the center of the circle about which the object moves.
Why is the direction of centripetal acceleration always perpendicular to velocity?
As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle. This would mean that the force is always directed perpendicular to the direction that the object is being displaced.
Is it possible that an object moving with an acceleration but with uniform speed?
Answer: It is possible. Explanation: If a body moves in a circular path, then it has constant speed but due to constant change in direction, velocity changes and the motion is accelerated.
Is it possible that a body moving horizontally with acceleration in vertical direction?
Yes, Its possible. A body projected at some angle will have horizontal motion, while Acceleration due to gravity “g” will be acting vertically down. For example: When a body tied with rope moves in a vertical circular path, at the bottom most point velocity is horizontal and acceleration is in the vertical direction.
What is an object moving in a certain direction called?
(b) an object moving in a certain direction with acceleration in the perpendicular direction. (a) The given statement is possible. The word acceleration implies a change in the object’s velocity. One example of this is vertical particle projection.
Why is acceleration perpendicular to the direction of the body?
The acceleration of the body is along the radius, while the direction of the body is along the tangent. Radius is perpendicular to tangent. Thus, acceleration is perpendicular to the direction.
What happens when an object is thrown in upward direction?
When an object is thrown in upward direction, at the maximum height the velocity of the object becomes zero but still in that condition a constant acceleration due to gravity is working. (b) Object moving in a certain direction with an acceleration in perpendicular direction is possible; in case of circular motion.
What is the direction of centripetal acceleration in circular motion?
When an object is moving along a circular motion its path is along the circle tangent but the centripetal acceleration is towards the circle radius. We understand that with the radius, a tangent still makes a right angle. So when the object in a circular motion, the velocity and accelerations are in a mutually perpendicular direction.
