The motion of an object can be described by its speed and direction. Speed and direction together determine an object’s velocity. 0457200motion position gravityvelocityspeeddirection0motion position gravityvelocityspeeddirectionFill in the blanks with words from the box below. ________________ is an object’s location, or place.________________ is a change in an object’s position as compared to objects around it.________________ is a measure of the distance an object travels in a certain amount of time.Motion has both speed and ___________________.___________________ is a measure of speed in a certain direction.Forces such as friction and ____________________ can change the velocity of moving objects.Circle the letter that best answers the question or completes the sentence.Which is a change in an object’s position as compared to objects around it?directionC. speedmotionD. velocityWhich measure of the distance an object travels in a certain amount of time?directionC. speedmotionD. velocityWhich tells you which way an object is moving? directionC. speed motionD. velocity Which is a measure of speed in a certain direction?speedC. motionvelocityD. direction Study Guide B Ch 16What are gravity and friction?Main Idea. Forces are pushes or pulls that cause objects to change their motion. Friction and gravity are two important natural forces. Write answers to the questions on the lines below.What kind of force moves an object away?_______________________________________________________________________In what ways can a force change the motion of an object?_______________________________________________________________________How does friction help us move from place to place?_______________________________________________________________________An apple falling from a tree to the ground is an example of _______________________.A person pushing a heavy box across the floor, which moves very slowly, is an example of _____________________.Why do racecars and airplanes have sleek (slim) shapes?Why do objects fall to Earth?________________________________________________________________________Label the examples of these simple machines. 9. 10. _______________ _____________ _____________-122829382137Vocabulary0VocabularyCh 16 REVIEW and TEST PREP Complete each sentence with a term from the box.1333540640forcefrictiongravity inclined planelevermotionpositionpulleyscrewsimple machinespeed velocitywedgewheel and axleforcefrictiongravity inclined planelevermotionpositionpulleyscrewsimple machinespeed velocitywedgewheel and axle An object’s ________________ is its location, or place.The distance traveled in a unit of time is called __________.The force of ____________ pulls things toward Earth.A simple machine made up of two inclined planes is a/an _______.An object’s change in position when compared to things around it is called ________________.The force that slows the motion between two surfaces that touch each other is called ________________.A push or pull is a/an _________________.A simple machine made up of a slanted surface is a/an _________.An object’s _________________ includes its speed and direction.10.
