Question

define the term "uniform acceleration". give one example of a uniformly accelerated motion

Answer 1

when an object moves ina straight line ,the velocity increases or decrease by equal amounts in equal intervals of time,then the acceleration of the object is said to be uniform .The motion of freely falling body is an example for uniform accerleratedmotion

Answer 2

HEY MATE...!!!✌

To understand the concept of uniform acceleration we need to understand the concept of Acceleration first.

✍ Acceleration

• Acceleration is the  rate of change of velocity with time.
• It  is defined as change of velocity of body per unit time.
• SI unit of acceleration is m/s²
• It is Vector Quantity.
• Acceleration = Change in velocity / time

       = Final velocity - Initial velocity / time

       = v - u / t

✍ Types of Acceleration

1. Uniform Acceleration

• If the velocity changes in equal amounts in equal time of intervals and the object travels in a straight line than the uniform acceleration take place.
• Example - A ball rolling down a slope

2. Non-uniform Acceleration

• If the velocity changes in an equal amount in unequal intervals of time and object travels in straight line then non uniform acceleration take place.
• Example - If a car covers 10 meters in first two seconds, and 15 meters in next two seconds.

✏ Zero Acceleration -  

• If the change in velocity is zero that is either object is at rest or moving with uniform velocity than zero acceleration will take place.

✏ Positive Acceleration -  

• When velocity of a body increases then positive acceleration take place.
• i.e v > u

✏ Negative Acceleration -  

• When velocity of a body decreases the negative acceleration take place.
• It is in the opposite direction of velocity.
• i.e v < u
