Speed
What is the speed equation?
Speed = distance / time
An object is in motion if….?
It’s distance from another object is changing.
What is acceleration?
The fate and which velocity changes
How do you calculate slope?
Rise / run
What is velocity?
Speed at a given direction
What is instantaneous speed?
Rate at which an object is moving at a given instant time.
What is reference point?
A place or object used used for comparison to determine if something is in motion.
If an object’s speed increases then is it accelerating or decelerating?
accelerating
How do you calculate acceleration?
Final speed - initial speed / time
In everyday language acceleration means?
“The process of speeding up”
What is the slash known as in distance / time
per
What are some units of measurements?
Cups, miles, and pounds
If an object’s speed is slowing down is it accelerating or decelerating?
Decelerating
Is speed vs time, is the line curved or straight
Straight
If an object is changing its position is it in motion?
Yes, it is in motion
How can you find the average speed?
Total distance / total time
Scientists use SI units to describe what other than length?
Quantities
True or false: Acceleration is also a change in direction at the same speed.
False
What are the two ways to graph acceleration
Speed x time
Distance x time
In science, acceleration refers to what?
Increasing speed, decreasing speed, or changing direction
How do you know the velocity of an object?
When you know both the speed and direction of an objects motion.
In French, what is the International System of Units called?
Système International
How can a car be accelerating if it’s speed is constant at 65 km/h?
It follows a gentle curve in the road or changes lanes
What does the X and Y represent when graphing motion
X = Time
Y = Distance
True of false: When graphing motion, if some objects don’t travel at constant speeds then they will not have different slopes.
False
