GRAPH 1

As the objects is dropped it accelerates.You can see this by the bend at the start.After the object has reached terminal velocity the object stays at the same speed.This is represented by the straight line from 0.25 to 0.7.

At this point the object abruptly stops. This is because it has hit the ground.But then the object bounces back up and this bounce is represented by the ascending line after the 0.6 second mark.

The bounce reaches its peak height at around the eight second mark. After I falls back to the ground as it is shown by the arc at the end of the graph.

ACCELERATION OF GRAVITY

• The acceleration of gravity is 9.8m/s
• This is for the the gravity of the earth
• There has to be no other force imposed upon the object
• The only force that is imposed on the object is gravity
• No matter what the weight of an object is it will still fall at the same rate

GRADIENT OF ACCELERATION

GRAPH OF ROCKET RE-ENTRY

This chart is 1000 feet to nautical miles. The re-entry pod falls at a relatively even pace for the first quarter of the graph.The pod decelerates down and there is a point where the astronauts suffered 6.35 g.

The pod keeps at a relatively constant height before rising up and dropping down again. Parachutes are opened and the pod decelerates and stops when it lands

ROSETTA ORBITOR

Rosetta is a robotic space probe built and launched by the European Space Agency to perform a detailed study of comet 67P/Churyumov–Gerasimenko. Launched in 2 march 2004 it is final found its destination comet 6 august 2014

The craft is orbiting the comet at a speed of 1 m/s. It is the first robot to orbit and the land on a comet.The orbiter is designed to make the most detail study of a comet in human history.

INTERESTING FACTS

• The spacecraft weighs less than 150 kg.
• More than 2000 people have working with or on it.
• The spacecraft needs drills to secure itself on the comet
• It to more than ten years to reach its destination
• The robot lander weighs the same as a human child

SPEED AND VELOCITY

• The craft orbits at 1 m/s
• Comet escape velocity is 0.5m/s
• Craft needs harpoonds and drills.
• To secure itself to the comet.
