when wil you say a body is in (I) uniform acceleration? (ii) non uniform acceleration?
Answers
Answer:
Explanation:
1] uniform motion
When a body is changing its velocity at a constant rate, then the body is said to be moving with uniform acceleration.
2] non uniform motion
When a body is changing its velocity at different rates, then the body is said to be moving with non-uniform acceleration.
Answer:
Acceleration is defined as the rate of change of velocity with respect to time. Acceleration is a vector quantity as it has both magnitude and direction. It is also the second derivative of position with respect to time or it is the first derivative of velocity with respect to time.
Explanation:
Uniform acceleration
When an object is travelling in a straight line with an increase in velocity at equal intervals of time, then the object is said to be in uniform acceleration.
The free-falling of an object is an example of uniform acceleration.
Non-uniform acceleration
When an object is travelling with an increase in velocity but not at equal intervals of time is known as non-uniform acceleration.
Bus moving or leaving from the bus stop is an example of non-uniform acceleration.
