Note: You will most likely need a calculator and the physics formula sheet to complete this quiz.

Name:
1. If my mass is 10kg and 'g' is 9.8, what is my weight force?

N (Whole number)

2. What is the GPE of a satellite orbiting a planet given:

     Mass of satellite: 1000kg

     Mass of Planet:     6 x 1016 kg

     Radius of Orbit:     3 x 103 km

     Universal Gravitational Constant:    6.67 x 10-11

J (Whole Number)

3. A student performed an experiment to determine a value for 'g'. He used a 120cm long length of string and timed a period of 22.3 seconds for the pendulum to complete 10 oscillations. What was his experimentally determined value for 'g'?

ms-2 (Two decimal places)


4. Use the following information to calculate the value for 'g' on the surface of Jupiter:

     Mass of Jupiter:    1.9 x 1027 kg

     Radius of Jupiter:  7.15 x 104 km

     Universal Gravitational constant:    6.67 x 10-11

ms-2 (Two decimal places)

5. If I weigh 784N on earth, what is my weight on Mars assuming 'g' on Earth is 9.8 and 'g' on Mars is 3.7?

N (Whole Number)

6. What's the escape velocity of a 100kg satellite on a planet with a mass of 4 x 1022 kg and a radius of 6134km? Take the Universal Gravitational constant to be 6.67 x 10-11.

ms-1 (One decimal place )

7. Assuming that the normal value for 'g' is 9.8ms-2, what is the maximum acceleration an astronaut can sustain without exceeding the maximum safe 'g' force of 8g's?

ms-2 (One decimal place )

8. Using the following information about a rocket ship, determine how fast the rocket is travelling at the exact moment when the fuel runs out.

     Mass of Rocket (with fuel):    3.4 x 104 kg

     Mass of Fuel:         170 kg

     Velocity of Gases being expelled:    5.6 x 105 ms-1

kmh-1 (Whole Number)

9. A car of mass 1200kg travels around a corner of radius 167m at 65kmh-1. What is the magnitude of the centripetal force?

N (One decimal place )

10. A satellite of mass 80kg is orbiting a planet of mass 6.7 x 1021 kg at an altitude of 100km. If the radius of the planet is 6.134 x 106 m, what is the orbital velocity of the satellite taking the universal gravitational constant to be 6.67 x 10-11?

ms-1 (One decimal place )
