п»їOpen-ended Investigation (mass and force)

Aim: To exhibit the relationship between Mass, the force working on it, and acceleration simply by gathering info through investigations. Hypothesis: Because Mass increases, Acceleration Decreases. Therefore , Velocity is inversely proportional to mass. Advantages

A pressure is a force or move acting upon an object, as a result of its interaction with another object. Within a state of motion, an object experiences distinct forces which will influences it is movement. There are many different types of forces which will act upon a subject; a normal power, a gravitational force, the applied power of the object, and the force of rubbing. A normal pressure is the pressure which amounts the fat of an subject on a surface, it travels in the contrary direction while Gravitational causes but has the same degree. Gravitational forces are magnet forces in the Earth which pull a subject down to the Earth. The normal provides a balance which will keep the object on the surface. The applied pressure is the pressure which a subject applies on to another subject. On automobiles, the engine turns the wheels, making force on to the road in order to move. The frictional power is the force which takes place when two objects rub against the other person, forcing the thing to reduce or stop. Friction includes air amount of resistance and rough concrete, as they restrict the motion of vehicles. The experiment is exploring how mass affects velocity, using the equation Force sama dengan Mass by Acceleration. A trolley will be on a way and will be pulled by a force – a slotted mass, which will cause that to move due to being an out of balance force. The experiment will probably be repeated with several different masses added, and acceleration will probably be measured and compared to find the relationship among mass, pressure, and acceleration. The method I possess chosen is actually a method I think to accurately measure the speeding of different measured objects. Seeking the acceleration within a ticker timer involves computing the initially and last dots in the ticker tape, then calculating the time through the amount of intervals (ticks) that the recording has. Duplicating the experiment with different people allows me to assess and evaluate the effects of diverse masses. The force is definitely kept similar, as the slotted people which pull the cart are held the same over the whole try things out. The impartial variables involve variables that are changed by simply me, which are the masses. The dependent varying are variables which are transformed due to the 3rd party variable, these are the velocity, or in fact , the acceleration of the object. The controlled changing is stored the same through the entire whole try things out. The managed variable is a stringed slotted masses which usually pull the trolley.


A doll car or perhaps small wagon which is competent of having weights. Dumbbells of different masses. Preferably even more weights of the smaller mass and at least one or two of a larger mass, whatever would work. A small approx. 300g pounds with a lift which is used while the constant force, and string. A runway, to produce a homogeneous slope.

Ticker Timer, Carbon dioxide Paper

Whenever possible, a pulley or a great attachment which will mount the string off of the table.

Risk ASSessment

Danger of weights slipping on the ground and breaking feet, fingers, etc . This can be resolved by carefully observing the toy car, and getting rid of any weights if the experiment is not in progress. As the research ends when the small fat hits the ground, the toy car must not reach the final of the table. When carrying weights, they must be held with two hands and securely, in order to stop them by slipping towards the ground. Hazard of car/cart dropping to the ground

A towel or maybe a soft surface can be placed in the grass where the toy car may possibly drop, to be able to protect the auto from influence. Method

1 . Weigh the trolley. Record your end result.

2 . Setup the catwalk with a significant slope, which has a buffer or maybe a soft area at the bottom to catch the trolley in...
