background image 1 Physical Science Study Guide Which of the following is classified as an electrical force? a. The force holding stars together in a galaxy b. The force attracting the electrons to the nucleus in an atom. c. The force holding the sun and planets together in a solar system. d. The force holding protons and neutrons together in a nucleus. According to principle of non-contradiction, if two ideas contradict each  other, which of the following statements is true? a. both statements must be false b. both statements must be true c. one statement must be false and the other statement must be true  d. one statement must be false e. the simplest statement must be true Which is easier to accelerate? a. the cannonball requires more force to accelerate it as much as the  marble.
background image 2 b. The cannonball requires less force to accelerate it as much as the  marble. c. The cannon ball and the marble will accelerate the same amount in  response to the same force. As a body moves higher and higher above the surface of the earth… a. its weight increases  b. its mass increases c. its weight decreases d. its mass decreases e. both its weight and its mass decrease All objects weigh less near the surface of the moon than the same objects  weigh near the surface of the earth. This is because… a. the moon has less mass than the earth b. the moon has a smaller radius than the earth c. this is less air on the moons surface d. the universal gravitational constant is smaller near the moon e. the buoyant force on the moon is greater than on earth
background image 3 A ball thrown up and then falls back until it reaches the ground. during its  flight, which of the following best describes its motion? a. its speed is constant, but not its velocity b. its acceleration is constant, but not its speed c. its mass is constant, but not its acceleration d. its force of gravity is constant, but not its mass e. none of the above Halley’s comet is constantly falling towards the Sun but “keeps missing”  because a. it is moving too slow  b. it is moving too fast c. it is moving “sideways” d. it is both moving sideways and moving at the right speed e. Halley’s comet is not falling towards the Sun A raindrop, as it falls to the ground, reaches a speed known as terminal  velocity where the speed of the raindrop is neither increasing nor
