What is the term for the rate at which distance is covered?

What is the unit of acceleration?

What would the distance-time graph look like for an object traveling at a constant speed?

A car travels from 0 m/s to 20 m/s in 4 seconds. What is its acceleration?

What is the velocity of an object that travels 96 m in 8 seconds?

Which of the following graphs would represent an object that is accelerating?

Motion and Speed

The rate at which distance is covered is called speed.
The SI unit for length or distance is meter (m).
The unit of velocity is meters per second.
The unit of acceleration is meters per second squared.

Graph Analysis

A horizontal line on a distance-time graph indicates moving at constant speed.
A curved line on a distance-time graph indicates changing speed.
A d-t graph represents the relationship between distance and time.

Acceleration

Acceleration is the rate at which velocity changes.
Deceleration is the rate at which velocity decreases.
Acceleration is measured in meters per second squared.

Distance and Displacement

Distance is the total length traveled by an object.
Displacement is the shortest distance between the initial and final positions of an object.
Displacement has both magnitude and direction.

Velocity and Speed

Velocity is the rate of change in displacement with respect to time.
Speed is the rate at which distance is covered.
Velocity has both magnitude and direction, while speed has only magnitude.

Problem-Solving

To calculate speed, use the formula speed = distance / time.
To calculate velocity, use the formula velocity = displacement / time.
To calculate acceleration, use the formula acceleration = (final velocity - initial velocity) / time.

Graph Interpretation

A graph with a steep slope indicates high speed.
A graph with a shallow slope indicates low speed.
A graph with a horizontal line indicates constant speed.
A graph with a curved line indicates changing speed.

This quiz assesses understanding of motion concepts, including speed, acceleration, and relative motion, based on a graphical representation of runners and an object's movement.
