Objective 5 • Motion, forces and energy • Basically the physical part of science • There is 11 questions on this objective.
Objective 5 The Pioneer 10 spacecraft was launched in March 1972 to explore the solar system. Pioneer 10 has continued on its journey and is now traveling beyond the solar system. Which statement best explains why Pioneer 10 continues to travel farther out into space? A For every action force, there is an equal and opposite reaction force. B Objects in space accelerate at a greater rate than objects on Earth. C The force of the solar wind propels objects through space at a constant speed. D Objects in motion will remain in motion unless acted on by unbalanced forces.
Objective 5 A 2.25 kg fish swims in a pond at a constant rate of 56 meters in 96 seconds. What is the fish’s approximate speed? F 0.020 m/s G 0.40 m/s H 0.58 m/s J 1.7 m/s
Objective 5 The ball in the diagram is moving at a speed of 12 m/s. What is the momentum of the ball in kg · m/s? Record and bubble in your answer to the tenths place on the answer document.
Objective 5 A person uses a force of 600 N to lift a box from the ground to the top of the ramp shown. Another worker uses a force of 300 N to push the same box up the complete length of the ramp. What is the approximate percent efficiency of the ramp? A 17% B 23% C 77% D 83%
Objective 5 In which of the following circuits will all of the remaining lightbulbs continue to operate if the fifth lightbulb fails?
