Definitions
The change in the position of an object is known as this.
Displacement
This is where an object is located relative to a starting point.
Position
The metric units for distance and displacement.
meter
Anna walks to the bathroom in 45 seconds. James walks the same distance in 30 seconds. Who has a lesser speed?
Anna
Bedford walks 10km west to the grocery store. He shops then walks back 10km east to his house. What distance did he cover?
20km
Motion is ______ meaning it depends on position compared to a specified point.
Relative
What a car is doing if on a distance vs time graph the line is going straight across (horizontally)
Car is stopped (distance staying the same)
The metric unit for time.
Second (s)
Danielle and Mykaila both run for 60 seconds. Danielle runs 140 meters while Mykaila covers 130 meters. Who has a greater velocity?
Danielle
Dayton runs 20m to the left, turns around and runs back 10m to the right. What is Dayton's displacement compared to his starting position?
10m
The amount an object moves is known as this.
Distance
The SLOPE (steepness) of a displacement vs time graph is equal to this.
Velocity
Velocity and speed typically use this unit in Physics.
m/s
Lower / Slower
The speed of a ball that travels for 1 second and covers 4.5 meters.
4.5 m/s
The rate at which an object's position changes. (No direction required)
Speed
John's total displacement if he walks 2 miles to the school, and then takes the short cut back home that is only 1 mile.
Zero (end up at starting point)
Acceleration is calculated using this equation.
Change in velocity over time
Antonio's change in velocity is 8 m/s in 10 seconds while his dog's change in velocity is 12 m/s in the same time. Which has a greater acceleration?
Antonio's dog.
The distance travelled by a car going 20 meters per second for a total of 5 seconds.
100 meters
An objects displacement in a certain amount of time.
Velocity
The units for acceleration.
m/s2
This is calculated using the change in displacement divided by the time it takes for the movement.
Velocity
If Joe runs 4 miles in 1 hour and Bob runs 2 miles in 20 minutes, who is faster?
Bob is faster
The acceleration of a skateboard starting at 10 m/s ending at 30 m/s over 10 seconds.
2 m/s2
