experimental error and also considering that gravity within itself is inconsistent on Earth the result may vary ±5% of the averaged 9.84m-2. Essential Theory: Where: * g= Acceleration due to gravity * G= Universal gravitational constant * M=Mass of the earth * d= distance from the centre of the earth or the radius Using values for Earth: * G= (6.67 x 10-11) * Mearth= (6.0 x1024)kg * dearth = (6.378 x106)m ∴g=(6.67×10-11)(6.0 ×1024)(6378 ×103)2 ∴g≈9.84ms-2 Fg=Fw Fg=GmMd2

section of the tray from which you took your samples, count the number of plants in a 5cm by 5 cm area. Record this count in your data table. 4. After the plants have dried, weigh and record the mass. 5. Allow the remaining grass to grow for one more week 6. Find the difference in the dry mass. This number is in grams of added carbon per five plants. Scale this up by using the number of plants growing in 25 cm. Then convert units of CM to m and also number of days between samples to years

of mass 50kg, stands 0.30 m from end A of a uniform plank of mass 8.0 kg and length 2.0 m. The plank is pivoted 0.50 m from end A, and an object of mass 5.0 kg is moved from and B until the plank balances. [pic] fig 1.1 i) On fig 1.1, draw and label the forces acting on the plank. ii) Show by using the principle of moments that the 5.0 kg mass must be placed 0.30m from end B in order for the plank to balance. (4) iii) The arrangement shown in Fig 1.1 has a maximum mass that

equipment. What is a pendulum? A pendulum is something that hangs from a fixed point known as a pivot and, when it is pulled back then released, it swings by the force of gravity acting upon it which is given by the restoring force and the pendulum’s mass, which in turn causes it to oscillate about the equilibrium position. The weight that hangs from the pendulum is called a “bob”. Inertia describes the fact that something in motion will stay in motion and, thus, something that is at rest shall stay

1. Coin in Cup We take the piece of paper or whatever it was away from the cup, therefore the coin falls into the cup due to Newton’s 1st law of Inertia. The coin, which was at rest, and once acted upon by pulling the paper away made the coin fall into the cup proving that the coin was acted on by some force making it fall. 2. Flying pucks When the picks are stable and are sitting on the table the are at rest, however once the puck is slung in to the lowest puck the inertia of the puck transferred

How does the equilibrium rule relate to Newton's first law of motion? Newtons first law states an object in motion will remain in motion unless acted upon by an outside for and an object at rest will remain at rest unless acted upon by an outside force. Either way the object will not have an acceleration and since F=ma, and a=0 there must not be any forces acting on that object either with means the forces are in equilibrium. If an ice skater is moving forward at constant speed, the gravity force

Writing in Mathematics 40. What does it mean if two quantities vary directly? What it means is that when two variables are related in this kind of way the ratio of their values always remain the same which the two variables are said to be in direct variation. 41. In your own words, explain how to solve a variation problem. When attempting to solve the best way to go about it would be to follow the 4 step process. The first step would be to write down the selected equation. All direct variation
