Is acceleration just an object speeding up?
No acceleration can be increase speed, decrease speed, or change direction
Measurement of acceleration are given in what units?
Meters per second per second, which is written as m/s2
How can you find acceleration with the use of a graph?
Calculate the slope of the line
What is a decrease in speed sometimes called?
Deceleration or sometimes negative acceleration
Measurement of speed are given in what units?
Meters per second or could be kilometers per hour
How do you determine slope?
Slope = rise / run (rise y-axis, run x-axis)
Is an object changing direction also accelerating?
Yes even if it is moving at a constant speed. I.e.car moving around a curve but maintaining same speed is considered accelerating because changing direction
What are two types of graphs that can help analyze the motion of an accelerating object?
Speed (velocity)-versus-time graph distance-versus-time graph
What is rise?
The vertical line dropped down from a point on the slanted line
Can an object continually accelerate?
Yes if it is continually changing directions. I.e. circular motion, moon acceleration around Earth because continuously changing direction as it revolves around Earth
If a speed versus time graph shows a slanted straight line, what does that mean
Speed is increasing at the same rate
What is run?
The horizontal line drawn from a point on the slanted line.
How do you calculate acceleration?
Acceleration = (final velocity -initial velocity) / time
If a speed versus time graph shows a horizontal line, what does that mean?
Constant speed
Why would a line not be straight?
Acceleration by different amounts each time period like a runner during a long race.
