For motion along a straight line,when do we consider the acceleration ...
When do we consider the acceleration to be positive or negative in motion along a straight line?
Acceleration can be considered positive or negative depending on the direction of motion.
Positive Acceleration:
- When an object is moving in the forward direction and its velocity is increasing, we consider the acceleration to be positive.
- For example, when a car is speeding up in a straight line, the acceleration of the car is positive.
Negative Acceleration:
- When an object is moving in the opposite direction of its initial motion, or if its velocity is decreasing, we consider the acceleration to be negative.
- For example, when a car is slowing down or coming to a stop in a straight line, the acceleration of the car is negative.
Example of a body in uniform acceleration:
- An example of a body in uniform acceleration is a freely falling object near the surface of the Earth.
- When an object is dropped from a certain height, it experiences uniform acceleration due to gravity (9.8 m/s^2).
- As the object falls, its velocity increases uniformly until it reaches the ground.
In conclusion, the direction of motion determines whether acceleration is considered positive or negative in motion along a straight line. Uniform acceleration is seen in scenarios like free fall, where the acceleration remains constant throughout the motion.
