Question

h) What is acceleration ? When do think the value of acceleration will be negtive ? what do you term it as ?​

Answer 1

Answer:

Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both.

Note that the units for acceleration are \dfrac{\text m/s}{\text s}

s

m/s

start fraction, start text, m, end text, slash, s, divided by, start text, s, end text, end fraction , which can also be written as \dfrac{\text m}{\text s^2}

s

2

m

start fraction, start text, m, end text, divided by, start text, s, end text, squared, end fraction. That's because acceleration is telling you the number of meters per second by which the velocity is changing, during every second. Keep in mind that if you solve \Large{a= \frac {v_f-v_i}{\Delta t}}a=

Δt

v

f

−v

i

a, equals, start fraction, v, start subscript, f, end subscript, minus, v, start subscript, i, end subscript, divided by, delta, t, end fraction for v_fv

f

v, start subscript, f, end subscript, you get a rearranged version of this formula that’s really useful.
