According to the Newton’s first law of motion, an object at rest or uniform motion continue its state unless an external force acting on it.

According to the Newton’s second law of motion, the force is equal to the mass time acceleration.

According to the Newton’s third law of motion, for every action there is always an equal and opposite reaction.

According to the Newton’s law of motion, the rocket continue at rest or uniform motion until a force applied on them. An unbalanced force must be formed to change the speed or direction of rocket. This unbalanced force is determined by the mass of the gases burned in the rocket and the speed that they are ejected from the motor. Finally the motion or reaction to the force formed, is equal and opposite direction of the thrust of the motor.

What is the effect of acceleration due to gravity on horizontal acceleration?

The question is the following:

An object accelerates from rest to $100\phantom{\rule{thinmathspace}{0ex}}\mathrm{k}\mathrm{m}$ per hour in $4.0\phantom{\rule{thinmathspace}{0ex}}\text{seconds}$. What fraction of the acceleration due to gravity is the car's acceleration?

From the question above, I can work out the acceleration (change in velocity over change in time) of the object using the given quantities: initial velocity ($0\phantom{\rule{thinmathspace}{0ex}}\mathrm{k}\mathrm{p}\mathrm{h}$), final velocity ($100\phantom{\rule{thinmathspace}{0ex}}\mathrm{k}\mathrm{p}\mathrm{h}$), and time ($4.0\phantom{\rule{thinmathspace}{0ex}}\mathrm{s}$).

But what does gravitational acceleration have to do with this? Is the answer related to friction created by the downward acceleration due to gravity?

A fan blade rotates with angular velocity given by $\omega}_{z}\left(t\right)=\gamma -\beta {t}^{2$, where $\gamma =5.00\text{}ra\frac{d}{s}$ and $\beta =0.800\text{}ra\frac{d}{{s}^{3}}$. (a) Calculate the angular acceleration as a function of time. (b) Calculate the instantaneous angular acceleration $a}_{z$ at $t=3.00\text{}s$ at t = 3.00 s and the average angular acceleration $a}_{av-z$ for the time interval t = 0 to t = 3.00 s. How do these two quantities compare? If they are different, why?
