Finding Acceleration Due to Gravity Using Ball Drop Method
Aim:
To calculate the acceleration due to gravity by dropping a ball from a
certain distance and recording the time
Hypothesis:
it is expected that the gravity should be within the same range for
each trial
Variables:
The independent variable = the distance
The dependent variable = the time
Controlled variables are: - the mass of the steel ball
- the position of the trip plate
-the length of the plumb line
Equipment:
- meter stick , half meter stick
- 1 steel ball
- Boss and clamp[IMAGE]
- Electronic Timing Device
- Release mechanism
- Plumb bob
-trip plate
Procedure:
- A steel ball was inserted between the jaws of the release mechanism
- The height was adjusted to 1 meter and half a meter, measured from
the bottom of the ball to the trip plate
- The plumb bob was used to locate the centre of the trip plate , to
ensure that the ball falls on it and to make sure the release
mechanism is perpendicular to the surface of the plate
- a circuit was made between the release mechanism, the trip plate and
the electronic timer. it was configured to start counting as soon as
the ball is released and to stop counting when it touched the plate
- The timer was switched on and RESET was pressed
- the thumbscrew was pressed to release the ball, it was held straight
rather than curved to achieve better results
- when the ball hits the plate, the spring comes up and the timer
stops
- the time was measured
- The distance ( independent variable) was varied by moving the clamp
upwards or downwards until the distance from the bottom of the ball
equals 0.5 m or 1 m
- The time was read from the electronic timing device
- The same steel ball was used through out the experiment and the

Boomilevers are most commonly built as right triangles, in order for them to withstand the most force. Naturally, this creates a hypotenuse, and also helps to define the device. If the tension member is the hypotenuse, then the device is known as a “tension boomilever.” In contrast, if the compression member is the hypotenuse, then it is known as a “compression boomilever.” When the testing of the boomilever begins, a weight is placed on the side farthest away from the base, or the distal end.
Earlier models just used a large weight on one end of a pivoting arm. The arm was pulled back the missile was placed and then let go.
The Physics of the Curve Ball Dad said that one of these days I would figure it out, but to this day I am still clueless. I have always been able to throw a decent curve ball; you don’t just throw 6 one hit games in your high school career without one. I have always wondered why and how the ball curves through the air, and it wasn’t until now that I have really had the chance to research a topic that has puzzled me for so long. I would bet that even pitchers in the “Big show” don’t know how or why, but they obviously have the talent and ability. I don’t know when the first curveball was thrown or who threw it, but there is a lot of controversy out there about whether or not the curveball really exists.
While Sam Colt was on the Corvo he came up with the idea of a revolving cylinder for a
A connecting rod subjected to an axial load F may buckle with x-axis as neutral axis in the plane of motion of the connecting rod, {or} y-axis is a neutral axis. The connecting rod is considered like both ends hinged for buckling about x axis and both ends fixed for buckling about y-axis. A connecting rod should be equally strong in buckling about either axis [8].
Bouncing Ball Investigation This is an experiment to investigate bouncing balls and how they behave in different situations. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. The first independent variable that will be tested.

Title: The Effects of Height, Length, Surface, Weight, Size, and Material on the Distance a Ball Rolls Down a Ramp Aim: The aim of this experiment is to investigate the factors that affect the distance a ball rolls when released from the top of a ramp. Variables:

Basketball dating back to December 21, 1891 has had practically everything to do with Physics. The trajectory of the ball, the gravity that brings it down after a shot, the wind force that alters the basketballs course to the basket, it all leads to Physics. Without Physics practically every sport known to man would be impossible to play, showing the importance of science.
