Exploring Motion and Time Concepts

Define rectilinear motion.

• Rectilinear motion is the motion of an object along a straight line.

• Rectilinear motion is the motion of an object that changes direction frequently.

• Rectilinear motion refers to the oscillatory movement of an object.

• Rectilinear motion is the motion of an object in a circular path.

What is periodic motion? Give an example.

• The movement of a car on a straight road.

• The growth of a tree.

• An example of periodic motion is the swinging of a pendulum.

• The rotation of a wheel.

How is speed calculated?

• Speed = Distance + Time

• Speed = Distance / Time

• Speed = Distance - Time

• Speed = Time / Distance

Explain the relationship between distance and time.

• Distance and time are directly related through the formula: Distance = Speed × Time.

• Distance is independent of time.

• Time can be calculated using Distance = Time × Speed.

• Distance is only affected by speed, not time.

What does a steeper slope on a distance-time graph indicate?

• It represents a constant speed.

• It indicates a lower speed.

• It shows no movement at all.

• It indicates a higher speed.

What is the difference between frequency and time period?

• Frequency and time period are inversely related; frequency measures cycles per second, while time period measures the duration of one cycle.

• Frequency is measured in minutes instead of seconds.

• Time period measures the speed of a cycle.

• Frequency is the same as time period.

If the time period of a pendulum is 2 seconds, what is its frequency?

• 1 Hz

• 0.5 Hz

• 2 Hz

• 0.25 Hz

What is the unit of frequency?

• Watts (W)

• Hertz (Hz)

• Volts (V)

• Joules (J)

Describe how to graph motion on a distance-time graph.

• Graph motion by plotting distance on the y-axis and time on the x-axis, connecting points to show speed.

• Use a bar graph to represent distance over time.

• Connect points with a straight line regardless of speed changes.

• Plot time on the y-axis and distance on the x-axis.

What is the significance of a horizontal line on a distance-time graph?

• The object is moving at a constant speed.

• The object is at rest.

• The object is changing direction.

• The object is accelerating.
