Mass and acceleration

Mass and acceleration experiment

If I increase the mass, the trolley will accelerate faster and slow down quicker once it goes off the ramp. Angle of the ramp is made with the leg part of the stool. 756 grams for the trolley and then we added 500 grams Acceleration= (final velocity-initial velocity)/ time takenDifference in gradients of the graph

The second attempt saw the trolley accelerate quicker than the first. It reached its maximum speed quicker.

1.5, 1.8, 3.0, 4.1, 5.1, 6.6, 7.9, 9.2, 10.6, 11.0, 12.9, 13.2, 14.6, cm

Average is 101.5/13= 7.8 cm/second

145 cm-0 cm/1.3 seconds = 111.5cm/per second per second or s2

3.3, 4.3, 5.5, 7.0, 8.7, 9.8, 11.2, 12.6, 14.2, 14.9, cm

149-0/1= 149 cm/s2 or 147 cm/s2 which is the similar

The gradient of the graphs are different. The first try in which the trolley was lighter saw the graph increase in speed slower. In the second try, the same maximum speed was reached in less time.

Our prediction was correct. Increasing the mass of the trolley caused the trolley to accelerate at a quicker rate.

We controlled the weight of all variables. The height and angle with the ramp was controlled (kept the same). Drag from the paper was approximately the same. We released it at the same place.

Because of the wheel, the direction of the movement was towards the north to northwest: we could not control it. The direction of the trolley was not controlled.

We found that the mass of the object will change the rate of its acceleration, and also decrease the time required for its deceleration due to friction once it is off the ramp. The heavier trolley should accelerate slower.

Vegetable People Practical

  Year 10 Genetics Experiment- Vegetable People Aim: To produce creative looking vegetable people based on the principles of probability and utilise Pun net squares with purpose. Method: 1.     The genotypes we chose are outlined on the sheet. 2.     We used Punnet squares to work out the possible genotypes and phenotypes of the children. 3.     We tossed a thin eraser to pick the phenotypes of the vegetable children. 4.     After working everything out, the vegetable parents and child were made and photos were taken. Discussion: Eyes Gender S S   S S   S p   S SS SS p Sp Sp p Sp pp p Sp Sp p Sp Sp p Sp pp SS+SS would result in 100% all...

COMPLETED VERSION Charles Perkins and the 1965 Australian Freedom Ride

Image
  Charles Perkins and the 1965 Australian Freedom Ride Charles Perkins was a champion for the rights and justice of Aboriginal and Torres Strait Islanders and an inspirational soccer player. He has described the Freedom Ride as the “the greatest and most exciting event [he had] ever been involved with in Aboriginal affairs”. A re-enactment and celebration of the Ride’s 50 th anniversary was held by the University of Sydney in 2015. That’s just last year. The original campaign was conceived and made possible through the occurrence of the civil rights movement in the U.S in the beginning of the 1960s. The Freedom Riders, as they were called in America, saw effective media coverage but were initially slow to achieve their purpose of desegregation on buses. Despite the violence and unrest it provoked, the tradition of direct action in civil rights was formed and solutions to segregation problems were implemented. Originally, University of Sydney students demonstrating out...
