Physical Science Chapter 15 Review Game Energy Forms of Energy Energy Conversions Problems 1 point 1 point 1 point 1 point 2 points 2 points 2 points 2 points 3 points 3 points 3 points 3 points 4 points 4 points 4 points 4 points 5 points 5 points 5 points 5 points Work is the transfer of this. 1 point Check What is energy? 1 point Back to Category Slide This is transferred by a force moving an object through a distance. 2 points Check What is the energy? 2 points Back to Category Slide The energy of motion. 3 points Check What is kinetic energy? 3 points Back to Category Slide A canoe with a mass of 30 kg floats downriver at 2 m/s. What is its KE? 4 points Check What is 60 J? 4 points Back to Category Slide An objectâ€™s gravitational PE is related to these things. 5 points Check What are height, mass, and acceleration due to gravity? 5 points Back to Category Slide The type of energy that increases when an object becomes warmer. 1 point Check What is thermal energy? 1 point Back to Category Slide The total of an objectâ€™s kinetic and potential energy. 2 points Check What is mechanical energy? 2 points Back to Category Slide The law of conservation of energy states this. 3 points Check What is energy cannot be created or destroyed, but can be converted to other forms? 3 points Back to Category Slide Energy and work are measured in this unit. 4 points Check What is Joule? 4 points Back to Category Slide The kinetic energy of an object is proportional to the square of its ___________. 5 points Check What is velocity? 5 points Back to Category Slide Energy that is stored due to its position or shape. 1 point Check What is potential energy? 1 point Back to Category Slide Energy resources that exist in limited amounts and, once used, cannot be replaced except over the course of millions of years. 2 points Check What are nonrenewable energy resources? 2 points Back to Category Slide Show how the units in the KE equation are equal to one Joule. 3 points Check 2 2 Kg-m /s 3 points = N-m = J Back to Category Slide This increases the elastic potential energy of a spring. 4 points Check What is compressing or stretching the spring? 4 points Back to Category Slide The KE of a moving cart with a mass of 74 kg and velocity of 52 m/s. 5 points Check What is 200,096 J? 5 points Back to Category Slide The PE of a 99 kg rock 5 m off the ground. 1 point Check What is 4851 J? 1 point Back to Category Slide The KE of a 12000 g chair sliding across the floor at 3 m/s. 2 points Check What is 54 J? 2 points Back to Category Slide The gravitational PE of a skydiver having a mass of 76 kg at the instant she is 1000 m in the air moving at a rate of 29 m/s. 3 points Check What is 744,800 J? 3 points Back to Category Slide The KE of a ball with a mass of 145 g moving horizontally through the air at a speed of 5 m/s at a height of 47 m. 4 points Check What is 1.81 J? 4 points Back to Category Slide The beginning KE of a pendulum at the highest point in its swing with a beginning PE of 45 J and a KE of 45 J at its lowest point in the swing. 5 points Check What is 0 J? 5 points Back to Category Slide
