Velocity of a wave in a tank at varying depths of water
Words • 1198
Pages • 5
An investigation into how the velocity of a wave is affected by varying the depth of the water it travels through. A tray was filled to a certain depth with water and one end raised to 45mm above floor level. The tray was placed on a folder 45mm high for each experiment so the height from which that end of the tray is dropped remains the same throughout the series of experiments. The sliding out of the folder from under…...
Under/over Speed Detection Using Contactless Tachometer
Words • 247
Pages • 1
The aim of the project is to design a contactless speed sensing device (tachometer) for a motor. Traditional tachometers require a physical contact to the shaft of the motor to measure the speed. In certain applications, where it is not possible to measure the speed directly, it is possible for a contactless tachometer to take the readings from a certain distance. This is the main motivation behind choosing this project. This contactless tachometer uses the IR transmitting and receiving technique.…...

Ticker - Timer Practical Report Introduction This practical is investigating the motion of a trolley as it is placed at the top of an inclined ramp, and is released to roll down the ramp. With the aid of a ticker-timer, the average speed and acceleration can be determined, and using this data, the amount of force that the trolley has acting on it, can be calculated. The ticker-timer is utilised to determine the distance that the trolley travels in each…...

Practical Investigation into the Horizontal motion of a Projectile
Words • 364
Pages • 2
The aim of this investigation is to determine the horizontal motion of a uniform particle when released down a ramp at varying speeds. The manipulation of speed will be achieved by positioning the projectile at different heights above a table, on a ramp. I believe that the horizontal component of the particle's travel will be proportional to its starting height, thus, if one is doubled so is the other. Equipment This experiment will require: Ball Bearing - projectile Ramp -…...
Investigation into factors affecting the speed of a car rolling down a ramp
Words • 4303
Pages • 18
The following investigation that I am going to embark on will involve the transfer of energy from one form to another. Usually when there is a transfer of energy from one component to another, these constituents are parts of machines or mechanisms, which are collectively classed as systems. In any one system there could be just one energy transfer or numerous transfers of energy. However, when we are dealing with systems, we must remember that there is no system that…...

Investigation of the Factors Affecting the Rate at Which an Object Falls 
Words • 2434
Pages • 10
All objects, when no force is acting upon them, shall remain at the same steady speed, without accelerating or decelerating; so if an object is still, it shall not move and if it is moving then it shall continue moving so long as no force is acting upon them. This was explained by Newton's first law. However it must also be noted that the meaning of "no force" may also be understood as "all forces acting upon a certain object…...

The aim of this experiment is to determine whether or not energy is conserved when a ball bearing is rolled down a slope. Six weeks of preliminary work have been carried out ensuring that measurements can be taken quickly with the correct instruments needed for the measurement. Previous knowledge of energy conservation says that energy cannot be created or destroyed. What factors need to be controlled or varied in this experiment? In this experiment many factors need to be considered,…...

Investigating factors that affect the bounce height of a squash ball
Words • 3303
Pages • 14
I have decided to investigate how the height from which a squash ball is dropped affects the height of its bounce. When a ball is dropped, it accelerates until it collides with the surface - an impact. It then recoils, and some of the energy is reflected back upwards, causing it to bounce. I believe that as the height from which the ball is dropped changes, the speed of the ball at the moment of impact will also change. This…...
Investigating the Effect of Varying the Perpendicular Height of a Ramp
Words • 1299
Pages • 6
Prediction of the relationship between the height used and the change horizontal distance travelled by the spherical mass. I believe that height is directly proportional to distance squared. This means that if the height is doubled the distance will quadruple. Explanation of the prediction in scientific terms. The formula to work out distance travelled is simply = average speed/total time, however there are many other formula used in working these two out. First the speed, or velocity must be obtained.…...

The aim of this investigation is to see how changing the height of a ramp affects the stopping distance of a toy car
Words • 4775
Pages • 20
I predict that if I increase the height of the ramp, the further the stopping distance would be. I feel that this is because the higher the ramp, the more G.P.E (gravitational potential energy) it will have. Therefore the more energy it will have, thus increasing the stopping distance of the car as it will take longer for the forces working against the car (i.e. friction etc) to stop it. In our investigation we will not be changing the mass…...

Determining the speed of light is something that has been a very long and trying process. No one scientist could determine such a thing. Galileo was the first noted scientist to attempt experimentation on the speed of light.

Every scientist performed their experiments differently based on the knowledge and ability they had at that time. Along…...
