Newton’s Laws of Motion are fundamental to understanding a dragster’s acceleration:

First Law (Inertia): An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by a force.
Second Law (F = ma): The force acting on an object is equal to the mass of the object multiplied by its acceleration. This law explains how a dragster’s powerful engine generates the force needed for rapid acceleration.
Third Law (Action-Reaction): For every action, there is an equal and opposite reaction. The force exerted by the dragster’s tires on the track propels the vehicle forward.

2.2. Calculating Acceleration

Acceleration is defined as the rate of change of velocity over time. The formula for calculating acceleration is:

a = (v_f - v_i) / t

Where:

a = acceleration
v_f = final velocity
v_i = initial velocity
t = time

For example, if a dragster starts from rest (0 m/s) and reaches a velocity of 100 m/s in 3 seconds, its acceleration would be:

a = (100 m/s - 0 m/s) / 3 s = 33.33 m/s²

2.3. Factors Affecting Acceleration
