Definitions
This term describes how fast an object is moving, regardless of direction
What is speed?
The formula for speed?
Speed=Distance/Time
The units for speed if distance is measured in meters and time in seconds.
What is meters per second (m/s)?
A cyclist rides 30 km in 2 hours. What is their average speed?
What is 15 km/h?
True or False: A car driving in a circle at a constant speed has changing velocity.
What is True?
This term describes both the speed of an object and the direction it is moving in.
What is velocity?
The formula for velocity when direction is included.
Velocity=Displacement/Time
In the formula Velocity=Displacement/Time , what are two possible units for time?
What are seconds or hours?
A car drives at a speed of 60 km/h for 3 hours. How far does it travel?
What is 180 kilometers?
You jog 3 km east and then 3 km west. If it takes you 30 minutes, what is your velocity?
What is 0 km/h? (since displacement is zero)
This quantity is needed along with speed to calculate velocity.
What is direction?
To find distance using speed and time, you multiply these two variables.
What is speed and time?
If a car travels 100 kilometers in 2 hours, the speed is measured in these units.
What is kilometers per hour (km/h)?
A person walks 200 meters in 50 seconds. What is their speed?
What is 4 m/s?
A boat travels 15 km east, then 15 km west, taking 2 hours in total. What is its speed?
What is 15 km/h?
True or False: Velocity changes when only the speed of an object changes, even if the direction
What is False?
How would you rearrange the speed formula to solve for time?
What is Time=Distance/Speed
A runner's speed is 5 m/s. If they run for 30 seconds, what units will the distance be in?
What is meters?
A train travels 100 miles in 2 hours going north. What is its velocity?
What is 50 miles per hour north?
A skateboarder rolls down a hill at 10 m/s. If they reach the bottom 5 seconds later, how far did they travel?
What is 50 meters?
What do we call a change in velocity over time?
What is acceleration?
When calculating velocity, this quantity must be measured in a straight line from start to finish.
What is displacement?
This unit could be used for speed when measuring the pace of a walking person.
What is kilometers per hour (km/h) or meters per second (m/s)?
An airplane covers 1,500 km in 3 hours. Calculate its speed in km/h.
What is 500 km/h?
Two cars are moving at 60 km/h in opposite directions. Do they have the same speed, velocity, or both?
What is same speed, different velocity?
