PHYSICS Vocab Squares FORCE & MOTION

FORCE WORD: PICTURE: DEFINITION: FORMULA: Force = mass x acceleration A PUSH OR A PULL ON AN OBJECT. ANYTHING THAT CAUSES THE SHAPE OR MOTION OF AN OBJECT TO CHANGE. FORCES CAUSE OBJECTS TO SPEED UP, SLOW DOWN, OR CHANGE DIRECTION. FORMULA: Force = mass x acceleration

BALANCED FORCE WORD: PICTURE: DEFINITION: FORMULA: N/A OPPOSING FORCES ARE EQUAL SO THAT NO CHANGE IN MOTION OCCURS. WHEN FORCES ARE BALANCED THE NET FORCE IS ZERO. FORMULA: N/A

N/A PRODUCE A CHANGE IN MOTION. WORD: PICTURE: UNBALANCED FORCE DEFINITION: PRODUCE A CHANGE IN MOTION. THE NET FORCE ON AN OBJECT IS NOT ZERO. FORMULA: N/A

The tendency of all objects to resist any change in motion WORD: PICTURE: INERTIA DEFINITION: The tendency of all objects to resist any change in motion (based on mass) FORMULA: Big Mass Small Mass Big Inertia Small Inertia N/A

WORD: PICTURE: NEWTON DEFINITION: THE SI UNIT FOR FORCE. FORMULA: N/A

NET FORCE PICTURE: WORD: DEFINITION: FORMULA: THE FORCE THAT RESULTS FROM COMBINING ALL THE FORCES EXERTED ON AN OBJECT. 25 N 10 N FORMULA: *Add if in same direction. *Subtract if opposite directions

N/A GRAVITY WORD: PICTURE: DEFINITION: FORMULA: THE FORCE OF ATTRACTION BETWEEN OBJECTS DUE TO THEIR MASSES. The larger the mass the greater the gravity. FORMULA: N/A

N/A WEIGHT A MEASURE OF THE GRAVATIONAL FORCE ON AN OBJECT. WORD: PICTURE: WEIGHT DEFINITION: A MEASURE OF THE GRAVATIONAL FORCE ON AN OBJECT. ITS VALUE CAN CHANGE WITH THE LOCATION OF THE OBJECT IN THE UNIVERSE. FORMULA: N/A

N/A MASS THE AMOUNT OF MATTER IN AN OBJECT. WORD: PICTURE: MASS DEFINITION: THE AMOUNT OF MATTER IN AN OBJECT. ITS VALUE DOES NOT CHANGE WITH THE OBJECT’S LOCATION IN THE UNIVERSE. FORMULA: N/A

WORD: PICTURE: INCLINED PLANE DEFINITION: A SIMPLE MACHINE MADE OF A FLAT SURFACE SET AT AN ANGLE THAT REDUCES THE AMOUNT OF FORCE REQUIRED TO MOVE AN OBJECT FORMULA: N/A

WORD: PICTURE: PULLEY DEFINITION: A SIMPLE MACHINE MADE OF A WHEEL AND ROPE USED TO CHANGE THE DIRECTION OF THE FORCE FORMULA: N/A

FRICTION WORD: PICTURE: DEFINITION: Types of friction: A force that appears whenever two objects touch each other. Friction opposes motion between two surfaces in contact. Causes heat, wear & tear, and slows object down. Types of friction: Sliding, rolling, fluid, static, wind resistance/drag

WORD: PICTURE: Motion DEFINITION: an object’s change in position relative to a reference point over a period of time Reference Point: stays still while object moves past it

WORD: PICTURE: Speed DEFINITION: the numeric relationship between a distance…and the time needed to move that distance -or- Distance divided by Time FORMULA: S= d t

Velocity The speed of an object in a particular direction WORD: PICTURE: Velocity DEFINITION: The speed of an object in a particular direction Speed + Direction - or - Synonyms: Distance Time + Direction rapidity, swiftness

Acceleration WORD: PICTURE: DEFINITION: Formula: (don’t memorize) the rate at which velocity changes; an object accelerates if its speed, direction or both change Formula: (don’t memorize)
