Calculating Speed + Distance Time Graphs

What is speed?

• Speed is the distance traveled per unit of time, usually measured in meters per second (m/s) or kilometers per hour (km/h).

• Speed is the rate at which an object accelerates over time.

• Speed is the total distance covered regardless of time.

• Speed is the maximum distance an object can travel in a day.

What is the formula for calculating speed?

• Speed = Distance × Time

• Speed = Distance ÷ Time

• Speed = Time ÷ Distance

• Speed = Distance + Time

What does a distance-time graph represent?

• A distance-time graph shows how the distance of an object changes over time.

• A distance-time graph shows the speed of an object at different times.

• A distance-time graph represents the acceleration of an object over time.

• A distance-time graph indicates the direction of an object's movement.

What does a horizontal line on a distance-time graph indicate?

• The object is moving at a constant speed.

• The object is accelerating.

• The object is at rest and not moving.

• The object is moving backwards.

What does it mean if a line on a distance-time graph goes back down?

• The object is moving away from its starting position.

• The object is returning to its starting position.

• The object is moving at a constant speed.

• The object has stopped moving.

How can you find the total distance traveled from a distance-time graph?

• By looking at the highest point on the graph

• By calculating the slope of the line

• By measuring the length of the graph

• By calculating the area under the line

What is a constant speed?

• Constant speed means the object covers equal distances in equal intervals of time.

• Constant speed means the object accelerates continuously over time.

• Constant speed means the object moves at varying speeds throughout its journey.

• Constant speed means the object comes to a complete stop after a certain distance.

What is the difference between speed and velocity?

• Speed is a vector quantity (magnitude and direction), while velocity is a scalar quantity (only magnitude).

• Speed is a scalar quantity (only magnitude), while velocity is a vector quantity (magnitude and direction).

• Speed and velocity are the same; both are scalar quantities.

• Speed is a measure of distance, while velocity is a measure of time.

How can you determine if an object is slowing down on a distance-time graph?

• If the slope of the line is increasing, the object is slowing down.

• If the slope of the line is constant, the object is slowing down.

• If the slope of the line is decreasing, the object is slowing down.

• If the slope of the line is negative, the object is slowing down.

How can you determine if an object is speeding up on a distance-time graph?

• If the slope of the line is decreasing, the object is speeding up.

• If the slope of the line is constant, the object is speeding up.

• If the slope of the line is increasing, the object is speeding up.

• If the line is horizontal, the object is speeding up.
