Describing Motion I. Motion

A. Describing Motion Motion – occurs when one object’s distance from another is changing. 1. Reference Point:  A place or object used for _____________ to determine if an object is in ______________

2. Relative Motion  In talking about motion, it is important to indicate your point of reference  Sun looks like it is moving in the sky when the earth is actually spinning and causing that apparent motion.  Usually, we consider motion with respect to the ground or the Earth

B. Calculating Motion 1. Speed Equation: speed = distance time  Use consistent units for distance and time ie. ________ and _________  Does not have a _____________!!!

2. Instantaneous Speed speed at a given instant 3. Average Speed= total distance total time Not necessarily the speed traveled at any given instant 4. Velocity- ____________ in a given ___________

Solving for speed & velocity  1) Draw _________  2) Known + Unknown Value  3) ____________  4) Plug- in  5) __________

Speed/Velocity Problems  1. Find the speed of a runner who sprints at 70 meters in 70 seconds?  2. Find the velocity of a swimmer who swims 215 meters in 130 seconds east?  3. Calculate the time it would take for a pig to wobble at 0.28 km at a speed of 0.14 km/s?  4. Find the time it would take for a car to travel 180 km east at a velocity of 70 km/hr?  5. Calculate the distance in meters a cyclist would travel in 6 hours at a speed of 12.0 km/hr?

5. Graphs In a distance vs. time graph, the slope is speed Constant speed = _________ line

 Constant speed?  Slowing down?  Speeding up?  Moving backward or back to start?

Momentum  A ___________ defined as the product of an object’s mass and it’s velocity  Solving for momentum Momentum= __________ x _________ Or p= _______________

Momentum Problems  1. Calculate the momentum of a 65 kg dingo running north at 12.2 m/s?  2. Find the momentum of a 12 kg rabbit hopping east at 8.2 m/s?  3. What is the mass of a bull with 123 kg x m/s momentum charging south at 20.5 m/s?
