IPS SEMESTER 1 FINAL EXAM STUDY GAME: FRONTIER

A group of students is playing tug-of-war. The students on both sides of the rope are pulling with equal force so that the rope is not moving. This is an example of

• unbalanced forces
• balanced forces
• acceleration
• displacement

A firefighter feels the hose pushing backwards onto him as he uses it to put out a fire. What is the most likely cause of this?

• The hose material is very elastic.
• Since the hose is at rest, it tends to stay at rest.
• The force exerted on the water equals the mass of the water times its acceleration.
• The escaping water exerts an equal and opposite force on the hose.

An astronaut is planning a trip to a newly-discovered planet. According to the Law of Universal Gravitation, the astronaut's weight on the new planet will be greater than his weight on Earth if:

• the new planet has less gravity than Earth.
• the new planet has the same gravity as Earth.
• the new planet has more gravity than Earth.
• the gravity of the planet doesn't matter. Weight is the same everywhere in the universe.
