Calculate kinetic energy of a 1.2 kg cart moving at 20.0 m/s.

Energy transformations that involve one transformation from one type of energy to another are called transformations.

One soccer player (a) is moving at 4 km/h when she kicks the ball while another soccer player (b) is moving at 8 km/h. what statement accurately compares their kinetic energy if they have the same mass? a) both soccer players have the same kinetic energy. b) player b has twice the kinetic energy of player a. c) player b has four times the kinetic energy of player a. d) their kinetic energy can't be compared without knowing their mass.

What is a possible explanation for a set of facts that can be tested by further investigations called
