1. which object has the greatest inertia? a. baseball b. a tennis ball c. a ping pong ball d. a bowling ball 2. how is an object mass related to the force needed to start the object movingly? a. mass is not related to the force needed b. the smaller the mass, the greater the force needed c. the greater the mass, the greater force needed d. the greater the mass, the smaller the force needed 3. the total of the forces acting on an object is called? a. net force b. inertia c. speed d. balanced force 4. what happens to the motion of an object when the forces acting on it are balanced? a. the motion changes direction b. the motion does not change c. the motion speeds up d. the motion slows down answer all questions and all

9. an object is moved from the outdoors, which is at a temperature of 100 ºf, to a room at a temperature of 70 º f. what happens to the object when it’s placed in the room with a lower temperature? the object gives off more energy than it absorbs until it reaches a new lower thermal equilibrium where the amount of energy absorbed and given off is the same. the object gives off the same amount of energy as it absorbs until it reaches a new lower thermal equilibrium where the amount of energy given off is greater than the amount of energy it absorbs. the object gives off more energy than it absorbs until it reaches a new higher thermal equilibrium where the amount of energy absorbed and given off is the same. the object absorbs more energy than it gives off until it reaches a new lower thermal equilibrium where the amount of energy absorbed and given off is the same.
