What is average speed?
Average speed is the total distance traveled divided by the total time taken.
What is speed?
Speed is the distance traveled per unit of time (how fast something traveled)
What does a distance-time graph represent?
It shows how far something moves over time.
What is Newton’s First Law of Motion?
Objects stay still or keep moving unless a force makes them stop or change direction.
How do you calculate average speed?
Average Speed = Total Distance divided by Total Time
What is velocity?
Velocity is speed with a direction (like "50 mph north")
How can you determine speed from a distance-time graph?
You can find speed by looking at how steep the line is.
What are balanced forces?
Balanced forces cancel each other out, so nothing moves.
If a car travels 300 km in 3 hours, what is its average speed?
100 km/h
How does direction affect velocity?
If the direction changes, the velocity changes—even if the speed stays the same.
What does a horizontal line on a distance-time graph indicate?
A flat line means the object stopped moving.
What are unbalanced forces?
Unbalanced forces make objects start moving, stop, or change direction.
What unit is average speed measured in? You may also give an example.
Average speed is measured in units like meters per second (m/s) or kilometers per hour (km/h).
Give an example of speed versus velocity.
Similar Example: A bike going 10 mph is speed, but a bike going 10 mph east is velocity.
How do you identify acceleration on a distance-time graph?
A curving line means the object is speeding up or slowing down.
How do balanced forces affect motion?
If forces are balanced, an object won’t move or will keep moving at the same speed.
Why is average speed useful?
Average speed is useful because it provides a simple way to describe how fast an object is moving over a certain period, regardless of changes in speed.
What does the slope of a distance-time graph represent?
The slope (steepness) of the line tells us the speed.
Give an example of unbalanced forces in action.
