A car travels east at 45 kilometers per hour.
• A bicycle moves 8 meters per second.
O A marble rolls 30 centimeters away from the table.
• A student walks 20 meters down the street.
A bicycle moves 8 meters per second.
On a position-time graph, which of the following does the value of the slope indicate about the object? (1 point)
• velocity
O change in position
O change in direction
O total distance
The value of the slope indicates the velocity of the object.
Which one
The value of the slope indicates the velocity of the object.
The statement that includes a description of velocity is: A bicycle moves 8 meters per second.
The statement that includes a description of velocity is: "A car travels east at 45 kilometers per hour."
To determine which statement includes a description of velocity, we need to understand what velocity is. Velocity is a vector quantity that describes the rate at which an object changes its position in a specific direction. It includes both the object's speed and the direction in which it is moving.
In the given statements, only the first statement provides both the speed (45 kilometers per hour) and the direction (east) in which the car is traveling. This combination of speed and direction makes it a description of velocity.
