In the study of the motion of bodies, it is known that when an object is allowed to fall freely under the influence of gravity, it usually accelerates downwards at 9.8m/s2. This is usually referred to as the standard gravitational acceleration on the surface of the earth. This…

In this lab experiment, we shall focus on the validation of this law by applying the behavior of an almost frictionless motion of a car on a horizontal aluminum track and a constant force T will be applied on the car. This motion will be recorded by a motion sensor and used to analyze this law.
From the experiment and data analysis above, a number of things can be noted. The value of gravitational acceleration in the constant mass of the moving system is greater than the expected value of 9.81m/s2. This means that an increase in the value of gravitational acceleration is directly proportional to the net force. An increase in the net force will cause an increase in the gravitational acceleration.
In the second experiment, the value of gravitational acceleration towards the sensor is higher as compared to the value of gravitational acceleration away from the sensor. An explanation to this phenomenon can be attributed to the fact that for an object at rest, the force of gravity acts on that particular objects but on the other hand, a counteractive force from the surface acts on it.
For an object on a slope, some of the gravitational force is acted upon by the gravitational force that is provided by the slope. The remaining force may force it to move down slope and hence the data collected. This proves that Newton’s second law is followed

In AC induction motors, only stator coils are power while rotor has no supplied power. In DC motors, either the stator is made up of permanent magnet or electrically excited magnet. Simple motors are electrical machines that work
From the results obtained from the data sheet the muzzle velocity is supposed to represent the initial velocity of the yellow plastic projectile. It is evident that the range depends on the initial velocity i.e. The higher the initial
The magnitude of that force depends on the objects velocity, increasing with increasing velocity. The underlying law is derived empirically rather than based on theory. For most situations, simple approximations usually suffice; the simplest one of them is the
Since, the acceleration is also correspondingly small in value compared to the true 9.8M/S2 gravitational pull (Wilson & Hernandez 87).
The acceleration value attained in this experiment is smaller than the true or
After collection, the data was loaded to computers for purposes of analysis using DataStudio software.
Every object fall with a similar gravitational acceleration assuming there is no air resistance. An object thrown downward or upward and one released from rest falls
For symmetric objects the moment of inertia I am given by, where β = dimensionless fraction that lies between 0 and 1. For a rectangular block of dimensions, a × b × c has a moment of inertia for a rotation about an axis normal to a × b face and passing through the center of the object. The moment of inertia is affected by the distribution of mass.
