Question Answer
The state in which one object’s distance from another object is movingMotion
A place or point used for comparison to determine if an object is in motionReference Point
A version of the metric system used by scientists all over the worldInternation System of Units (SI)
The SI unit for lengthMeter
The distance that an object travels per unit of timeSpeed
What is the formula (equation) used to find speedS = D/T; Speed = Distance/Time
Tell a metric unit for speedKm/hr, m/s
The overall rate of speed that an object moves, comparing the total distance traveled and the total timeAverage Speed
The rate of speed that an object is moving at a particular instant or timeInstantaneous Speed
Speed in a given directionVelocity
The steepness of a line on a line graphSlope
How do you calculate the slope of a line?Slope = Rise/Run
On a graph that shows Distance V/S Time, what does the slope of the line represent?The Speed
On a graph that shows Distance V/S Time, what does a steep slope mean?The speed is fast
On a graph that shows Distance V/S Time, what does a gradual slope mean?The speed is slow
On a graph that shows Distance V/S Time, what does a horizontal line mean?Slope = 0, so the object is not moving.
The rate at which the velocity of an object changesAcceleration
What are the three things that can cause acceleration?Increase in speed, Decrease in speed, or Change in direction
What is the formula (equation) used to find acceleration?A = (Final Speed - Initial Speed)/Time
What is the metric unit for acceleration?(m/s)/s or m/s2
What does it mean if an object has a positive acceleration?It is speeding up
What does it mean if an object has a negative acceleration?It is slowing down
What does it mean if an object has no acceleration (A = 0)?It is moving at a constant speed
