Steady Pace
A hiker walks 5 miles East and 2 miles West. This is the total distance traveled.
7 miles
A runner starts at the finish line, runs a full 400-meter lap, and stops. Their displacement is this.
0 meters
This term describes the rate at which an object's speed changes over time.
Acceleration
A hiker walks 8 miles North, then turns and walks 2 miles South. This is their displacement.
6 miles North
A plane flies 1,000 miles in 2 hours. This is its average speed.
500 mph
This is the standard unit of measurement for time in most physics calculations.
Seconds
A robot rolls 15 meters forward, then reverses 12 meters. Calculate its final displacement.
3 meters forward
A car at a red light turns green and reaches 20 m/s in 4 seconds. This is the acceleration rate.
5 m/s²
A treasure hunter walks 20 paces East, 5 paces West, and another 10 paces East. This is their total displacement.
25 paces East
This is the formula used to find acceleration.
Change in speed divided by time
If a bus travels 100 km at a constant speed of 50 km/h, it will take this many hours to arrive.
2 hours
A scout walks 10 km North, then turns around and walks 6 km South. This is their displacement.
4 km North
When an object is slowing down, it is often said to have this type of acceleration.
Negative acceleration or Deceleration
This is the displacement of a submarine that dives 500 meters South and then rises 200 North.
300 meters South
A swimmer goes 50m down a pool and 50m back. The total distance is 100m, but the displacement is this.
0m
To calculate distance, you must multiply these two variables together.
Speed and Time
A football player runs from the 20-yard line to the 50-yard line, then gets pushed back to the 40-yard line. Calculate their total displacement from where they started.
20 yards
If a ball is dropped and accelerates at 10m/s2, this will be its speed after 5 seconds.
50 m/s
An athlete runs 60 meters forward, overshoots the mark, and walks 5 meters back. This is their displacement.
55 meters forward
A cyclist accelerates from 0 to 12 m/s in 3 seconds. Their acceleration is this.
4 m/s²
A car travels 15 meters in the first second, 15 meters in the second second, and 15 meters in the third. This is the car's speed
15 m/s
A boat travels 20 miles East, then 20 miles West, then 5 miles East. This is its final displacement.
5 miles East
An object moving at a constant speed in a straight line has an acceleration of this.
0
A elevator goes up 10 floors, down 4 floors, and up 2 floors. Its final displacement from the starting floor is this.
8 floors up
A train travels 60 km in 1 hour, stops for 1 hour, then travels 40 km in 1 hour. This is its average speed for the whole 3-hour trip.
33.3 km/h
