Question

Define the term uniform acceleration. give one example of uniform acceleration motion ​

Answer 1

If an object's speed (velocity) is increasing at a constant rate then we say it has uniform acceleration.EG-BALL ROLLING DOWN ON INCLINED PLANE. MARK BRAINLIEST PLZ

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 - f 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
