If its distance from another object is changing, the object is in
What is motion
Slope=
Rise/ Run
What is the equation we use to calculate speed?
Speed = Distance / Time
the speed and direction of an object's motion
What is velocity.
What is the equation for acceleration?
What is Final speed- Initial speed/time
A place or object used for comparison to determine if something is in motion.
What is reference point
the steepness of a line on a graph
What is slope.
the distance the object travels per unit of time.
What is speed.
What is speed that does not change called?
constant speed
In science, what do we call slowing down?
What is deceleration or negative acceleration
This system of measurement used to communicate motion
What is International System of Units.
A horizontal line on a graph represents
no motion
the total distance traveled by the total time.
What is average speed.
If you know a car travels 40 km in 20 minutes westward, what is the velocity?
2 km/m west
What are the types of acceleration
increasing speed, decreasing speed, or changing direction.
The SI unit of length we use is called
What is meter.
constant speeds are graphed by using
What is a straight line
A reference point should always be
What is stationary
If a storm travels in the US 25 miles in 5 minutes, what is the storms velocity?
5 m/m west
What are the two graphs you can use to show acceleration?
What is direction-versus-time graph and speed-versus-time graph.
How do we calculate motion of an object?
We use the speed equation.
A distance-versus-time will have
A curved line
The unit for speed is
km/hr or m/h or m/s
As a roller coaster car starts down a slope, its speed is 4 m/s. But 3 seconds later, at the bottom, its speed is 22m/s. What is its average acceleration?
What is 6m/s2
