Exploring Time and Motion

What does a distance-time graph represent?

• A distance-time graph represents the temperature over time.

• A distance-time graph represents the relationship between distance traveled and time taken.

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

• A distance-time graph indicates the direction of travel.

How do you determine speed from a distance-time graph?

• Speed is found by averaging the distances.

• Speed is determined by the y-intercept of the graph.

• Speed is determined by the slope of the distance-time graph.

• Speed is calculated by the area under the graph.

What are the three main types of motion?

• Cyclic motion, linear acceleration, angular momentum

• Static motion, dynamic motion, uniform motion

• Linear motion, rotational motion, oscillatory motion

• Translational motion, vibrational motion, periodic motion

Define uniform motion with an example.

• An example of uniform motion is a car traveling at a constant speed of 60 km/h on a straight highway.

• A bicycle accelerating down a hill.

• A train coming to a complete stop at a station.

• A person jogging at varying speeds in a park.

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

• The object is accelerating.

• The object is at rest.

• The object is moving at a constant speed.

• The object is moving in a circular path.

Explain the difference between linear and non-linear motion.

• Non-linear motion only occurs in three-dimensional space.

• Linear motion is always faster than non-linear motion.

• Linear motion can only be horizontal, not vertical.

• Linear motion is straight-line movement, while non-linear motion involves curved paths.

What is the formula for calculating speed?

• Speed = Time / Distance

• Speed = Distance + Time

• Speed = Distance - Time

• Speed = Distance / Time

How can you identify acceleration on a distance-time graph?

• A straight line indicates constant speed.

• Acceleration is shown by a horizontal line.

• A vertical line represents acceleration.

• Acceleration is indicated by a curved line on a distance-time graph.

What type of motion occurs when an object moves in a circular path?

• Linear motion

• Rotational motion

• Translational motion

• Centripetal motion

Describe what a steep slope on a distance-time graph signifies.

• A steep slope indicates low speed.

• A steep slope shows no movement at all.

• A steep slope represents a constant speed.

• A steep slope signifies high speed.
