0.008 m =
1.2 x 106 ) =
2. A block of 700 g is pulled from rest on a horizontal frictionless bench by a steady force Fand
travels 7.0 m in 3.5 s.
a) (2 points) What was the acceleration of the block?
b) (2 points) Calculate the value of the force.
3. A rocket has a mass of 900 kg.

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

Asystematic approach to problem solving is called a (an)

Heterogeneous mixture with larger particles that never settle is
