I can describe an object’s motion by: Describe the motion in the picture Describe the Motion How long it takes (time) How far it travels (distance) How fast the object goes (speed) What path it follow (path/direction)

1.What forces are acting on the swing? 1.The pull of the chains 2.The pull of earth’s gravity 3.Both the pull of the chains and the pull of earth’s gravity 4.Neither the pull of the chains nor the pull of earth’s gravity Describe the Force

What causes the bike to accelerate? Pushes with forward force on pedals Why did the cyclist speed stay the same if she kept pedaling? counter forces pushing back: friction, force of air (air resistance) What is the flag show us? air resistance What helped the cyclist increase her speed? She pushed harder on the pedals How did the cyclist stop? She stopped pushing on the pedals Video Review
