1. A 2 kg toy car moves at a speed of 5 m/s. a. What is the kinetic energy of the car?
b. If a child applies a 3 N force for 2 m in the same direction the car is already moving, how much work is
done on the car?
c. What is the change in the car's kinetic energy from the applied force?
d. What is the final kinetic energy of the car? e. What is the velocity of the car after the child applies the 3 N force?

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called

What is the kinetic energy of a baseball moving at a speed of 40 m/s if the baseball has mass of 0.15 kg?

The receptor cells that convert light energy into neural signals are called
