Q-8 Give two points of difference between: Speed - Acceleration
Answers
Answer:
Acceleration and speed are fundamentally separate ideas. Every moving object has a motion that may be quantified in terms of speed. When an item begins to move, its initial speed is zero, and it gradually increases over time owing to acceleration.
Major differences between Speed and Acceleration:
- Acceleration is the rate at which speed changes, whereas speed is the distance travelled in a unit of time.
- The metric system uses metres per second (m/s) as the unit of speed and metres per second squared (m/s2) as the measure of acceleration.
- Acceleration is a vector quantity, whereas speed is a scalar quantity.
- Acceleration is related to both the rate of motion and the direction of motion, whereas speed is tied to the rate of motion alone.
Answer: The correct answer is speed is the distance covered in a unit of time while the acceleration is the change of speed.
Explanation: speed is considered as the scalar quantity and acceleration is the vector quantity while the unit of peed in the metric system is metersper second which is also written as m/s and the unit of acceleartion is metersper second square or also written as m/s2 where speed is related to the rate of motion while the acceleration is related to the rate of motion as well as the direction of motion and the ped is used to measure how fast is anything moving and also speed does not include the direction of the motion and the speed is alswayspositive and also during the circular motion the average peed does not become zero after the copleteing one round and as speed changes with the distance the acceraltion changes the velocity that is moving with the time and also its direction and that is why acceleration can also be negetive and positive both and accerelation also has the direction same as the velocity and the formula of accerlation is a = v/t so both acceeration and the speed are responsivble for determining the fastness and the direction of the motion with respect to time to find the average of any vehicle or any person who is in motion.
