Exploring Time and Motion Concepts

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

• second

• hour

• minute

• day

Convert 5 minutes into seconds.

• 60 seconds

• 120 seconds

• 180 seconds

• 300 seconds

Define the difference between position and distance.

• Position refers to the time taken to travel; distance is the direction of movement.

• Position is a measure of speed; distance is the area covered by an object.

• Position is the total distance traveled; distance is the speed of an object.

• Position is a point in space; distance is the length between two points.

If a car travels 100 meters east and then 100 meters west, what is its displacement?

• 50 meters west

• 200 meters east

• 0 meters

• 100 meters

How many seconds are there in one hour?

• 600

• 3600

• 7200

• 60

Explain why distance is a scalar quantity.

• Distance is a vector quantity because it has both magnitude and direction.

• Distance can be negative depending on the reference point.

• Distance is defined only in three-dimensional space.

• Distance is a scalar quantity because it has only magnitude and no direction.

If a person walks 300 meters north and then 400 meters south, what is their total distance traveled?

• 400 meters

• 500 meters

• 300 meters

• 700 meters

Convert 2 days into seconds.

• 86400

• 604800

• 432000

• 172800

What is the formula for calculating displacement?

• Displacement = Final Position - Initial Position

• Displacement = Distance / Time

• Displacement = Speed x Time

• Displacement = Initial Position + Final Position

If an object moves from point A to point B, how is its position defined?

• The position is defined by its coordinates in a reference frame.

• The position is irrelevant to the object's movement.

• The position is determined by the object's mass.

• The position is defined by its speed and direction.
