WIDUJE SCHOOL Physical Science Forces and Motion Lesson 93 5. A hockey puck slides with a constant velocity across a frictionless ice surface. In one paragraph, using your own words, describe the net force on the hockey puck and the observation which allowed you to draw that conclusion. Be sure to use proper spelling, grammar, and punctuation.​

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

What is the rate of change in a objects position?

How do we measure or think of speed in the united states?
