Motion & Time Challenge

What is the basic unit of time in the International System of Units (SI)?

• second

• millisecond

• day

• minute

How many seconds are in an hour?

• 3600

• 7200

• 5000

• 4500

If an object is moving at a constant speed, what would its distance-time graph look like?

• It would be a parabola.

• It would be a zigzag line.

• It would be a straight line.

• It would be a spiral.

Explain the concept of slope in a distance-time graph.

• The concept of slope in a distance-time graph is the color of the line on the graph.

• The concept of slope in a distance-time graph is the number of turns the object makes.

• The concept of slope in a distance-time graph is the temperature of the object.

• The concept of slope in a distance-time graph is the speed of an object, calculated by dividing the change in distance by the change in time.

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

• Object at rest

• Object in motion

• Object decelerating

• Object accelerating

How can you calculate the speed of an object using a distance-time graph?

• Speed = Gradient of the distance-time graph

• Speed = Area under the distance-time graph

• Speed = Slope of the distance-time graph

• Speed = Y-intercept of the distance-time graph

What is the relationship between the slope of a distance-time graph and the speed of an object?

• The slope of a distance-time graph shows the mass of an object.

• The slope of a distance-time graph represents the speed of an object.

• The slope of a distance-time graph is unrelated to the speed of an object.

• The slope of a distance-time graph indicates the acceleration of an object.

If a distance-time graph has a steep slope, what does it indicate about the object's speed?

• The object's speed is zero.

• The object's speed is low.

• The object's speed is high.

• The object's speed is constant.

What does a curved line on a distance-time graph indicate about the object's motion?

• The object is stationary

• The object's motion is changing its speed.

• The object is moving at a constant speed

• The object is accelerating

How can you determine the acceleration of an object from a distance-time graph?

• Calculate the slope of the distance-time graph to find the velocity, then calculate the slope of the velocity-time graph to determine the acceleration.

• Use the y-intercept of the distance-time graph

• Find the maximum value on the distance-time graph

• Determine the area under the distance-time graph
