Types of Motion
the change in an object's position
What is Motion?
a push or pull of one object on another through direct touch
the resistance to a change in motion
What is inertia?
the motion described from a particular reference point
What is relative motion?
an object's location or place
What is position?
a push or pull on an object without direct touch
What is noncontact force?
What is Newton's third law?
the appearance of motion
What is apparent motion?
a back and forth or up and down motion
What is vibration?
friction and tension are examples of this type of force
What is contact force?
the law that states that objects keep doing what they are doing unless acted upon by forces
What is Newton's First Law?
you watching a pop fly baseball from the stands at a baseball game describe the baseball location differently than the player on the field catching the ball is an example of this
What is relative motion?
the motion of an object along a line or a path from one position to another
What is translation?
electricity, magnetism, and gravity are examples of this type of force
What is noncontact force?
the law that states the greater the mass of an object, the greater the amount of force needed to accelerate the object
What is Newton's second law?
movies give the effect of this type of motion because of the high speed at which each image is shown
What is apparent motion?
the motion of an object around a central point
What is rotation?
the area surrounding an object in which a noncontact force is active
What is Newton's second law of motion?
a motionless place or object used for comparison with a moving object
What is a reference point?
a force that opposes motion
What is friction?
a person driving in a car will keep moving forward if the car comes to a sudden stop is an example of this law of motion
What is Newton's first law of motion?
a cymbal being struck demonstrates this type of motion
What is vibration (it quivers back and forth after being struck)?
a pulling force that resists stretching
What is tension?
a spinning top demonstrates these two types of motion
What is rotation (it goes around an axis) and/or translation (it moves across the floor as it spins)?
the air pushing against a parachute is this type of force
What is friction?
a plane flying demonstrates these two types of motion
What is translation (the plane moves in a line from place to place) and/or rotation (the propellers go around a central axis)?
a rope in a game of Tug of War is example of this type of force
What is tension?
a mixer's spinning beaters demonstrate what two types of motion
What is rotation (the beaters spin around an axis) and/or translation (a cook moves the beaters through the batter)?
a person falling out of a tree is an example of this type of force
What is gravity?
the ground during an earthquake demonstrates these two types of motion
What is vibration (the earth moving up and down) and/or translation (if the earth splits)?
