when distance of an object changes in relation to another object
What is motion?
the formula for calculating speed
What is:
Speed = Distance/Time
the rate at which velocity changes
What is acceleration?
A train travels 168 km in 4 hours. Find its speed.
What is 42 km/hr?
The graph represents this.
What is increasing speed (positive acceleration)?
a place or object used for comparison to determine if something is in motion
What is a reference point?
the speed and direction of an object's motion
What is velocity?
the formula for calculating acceleration
What is:
Acceleration = Final velocity - Initial velocity/Time
The bus travels from Montessori Academy to Chambersburg YMCA for phys ed at a speed of 50 km/hr and returns from the YMCA back to school at a speed of 30 km/hr. Find its average speed during the journey.
What is 40 km/hr?
The graph represents this.
What is decreasing speed?
a system of measurement based on multiples of ten and on established measures of mass, length, and time
What is the International System of Units (SI)?
one 1,000th of a meter
What is a millimeter?
another word for decreasing speed
What is deceleration?
Rachel traveled 240 km in 4 hours by train and then traveled 120 km in 3 hours by car and 3 km in 1/2 hour by cycle. What is the average speed during the whole journey?
What is 48.4 km/hr?
Look at the graph showing a car trip. Choose the part of the trip in which the car was traveling at the slowest rate.
What is part iv?
the basic SI unit of length
What is the meter?
4,000 m = ______ km
What is 4 km?
Acceleration refers to one of three types of movement, including:
1. increasing speed
2. ________________________________
3. ________________________________
What is decreasing speed and change in direction?
A roller coaster is moving at 25 m/s at the bottom of a hill. Three seconds later it reaches the top of the hill moving at 10 m/s. What is the acceleration of the coaster?
What is -5 m/s2?
A ball is thrown vertically into the air. When the graph touches the x-axis, this is happening.
What is the ball stops rising in the air and begins to fall?
the distance an object travels in one unit of time
What is speed?
20 m = ________ mm
What is 20,000 mm?
This graph is showing a straight line as the velocity increases. The straight line represents this.
What is a constant rate of change?
If a train going 60 m/s hits the brakes, and it takes the train 1 minute 25 seconds to stop, what is the train’s acceleration?
What is -0.71 m/s2?
Use the graph to determine Marie's rate of acceleration during her trip to work.
What is 0.0125 mi/min2?
