—change in velocity divided by the time for the change to occur; it can include an object’s speeding up, slowing down, and/or changing direction. B. Acceleration can be if you know how an object’s velocity has changed during a given time period. 1. The formula for calculating is: acceleration = final speed – initial speed/time or a = (sf – si )/t. a. The unit of acceleration is distance divided by time squared; in SI units, acceleration is given as (m/s 2 ). b. Acceleration is when an object speeds up and when an object slows down. 2. Accelerated motion can be with speed on the vertical axis and time on the horizontal axis. a. An object that is speeding up will have a line on a speed-time graph that slopes . b. An object that is slowing down will have a line on a speed-time graph that slopes . c. A horizontal line would indicate acceleration of , or constant speed.

Juju.01) 5 geologic events a group of students designed an experiment in an ice rink to represent the solar system. the steps of the experiment are listed below. 5: geologic events 1. choose a student to represent the sun. the planets are represented by two tennis balls. 2. ask the student to hold the tennis balls in each palm and spin on the ice with arms stretched out. 3. ask the student to draw in the arms after about 10 spins. 4. observe the student's arms rotate faster when they are closer to the body. 05 geologic events enors) the experiment most likely demonstrates that (2 points) 07 discussion-based sessment/module planets exert gravitational force on the sun the sun exerts gravitational force on the planets 3.07 discussion-based ssessment speed of a planet depends on its distance from the sun new version available!
