Question

uniform acceleration means the velocity of the body is either increasing or decreasing changing at a constant rate TRUE OR FALSE? thank youu

Answer 1

False.

Step-by-step explanation:

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of final speed from the initial speed all over time.

Hence, if we subtract the final speed from the initial speed and divide that by the time, we can calculate an object’s acceleration.

Mathematically, acceleration is given by the equation;

`Acceleration (a) = (initial speed - final speed)/(time)`

`a = (v - u)/(t)`

Where,

a is acceleration measured in
`ms^(-2)`

v and u is initial and final speed respectively, measured in
`ms^(-1)`

t is time measured in seconds.

Additionally, acceleration is a vector quantity because it has both magnitude and direction.

Hence, uniform acceleration means the velocity of the body is increasing at a constant rate. For example, an object or body that is experiencing a free fall in a uniform gravitational field is said to be in uniform acceleration.
