Which of the following is accelerating?
An object moving with a constant velocity.
An object moving along a curve.
None
An object moving on a straught line with a constant speed.
An object moving along a curve experiences centripetal acceleration.
we know that velocity is either change with magnitude or direction also.
and Acceleration is rate of change of velocity.
SO when object move along a curve or circular path, object having same magnitude but change the direction continuosly so it is accelerating.
When object move along straight path object has same direction and may depend only magnitude.
The object moving along a curve is accelerating.
To determine which of the options is accelerating, let's first understand the concept of acceleration. Acceleration is a measure of how quickly an object's velocity changes. In other words, it is the rate at which an object's velocity is increasing or decreasing over time.
Now, let's analyze each option one by one:
1. An object moving with a constant velocity: If an object has a constant velocity, it means its speed and direction are not changing. Thus, there is no acceleration in this case. Therefore, this option is not accelerating.
2. An object moving along a curve: When an object moves along a curve, its direction is changing. Since velocity is a vector quantity that includes both speed and direction, any change in direction indicates a change in velocity. Therefore, when moving along a curve, the object is accelerating.
3. None: This option does not provide any information about the object's motion. Without knowing anything about the object's velocity or any changes in its velocity, we can't determine if it is accelerating or not. Therefore, we cannot conclude if this option is accelerating or not based on the given information.
4. An object moving on a straight line with a constant speed: While the object in this option is moving with a constant speed, there is no mention of any changes in its direction. Without any change in direction, there is no change in velocity, and hence, no acceleration. Thus, this option is not accelerating.
In conclusion, out of the given options, the only one that is accelerating is the object moving along a curve.
