Nafes-Grade 6-Motion

Which of the following best describes the position of an object?

• Its mass and weight

• Its location relative to a reference point

• Its temperature and color

• Its speed only

What does distance measure in terms of motion?

• How fast an object moves

• The straight-line path between two points

• The total length of the path traveled by an object

• The direction of motion

Which scenario shows a correct use of a reference point?

• Using a moving car to measure the position of another moving car

• Using a stationary tree to describe the position of a cyclist

• Using the moon to measure the distance between two houses

• Using temperature changes to describe motion

When does an object appear to be at rest relative to a reference point?

• When it moves at a constant speed

• When its position does not change relative to the reference point

• When it accelerates

• When its weight increases

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

• km/h

• m/s

• N/m

• m²/s

What is the key difference between speed and velocity?

• Velocity includes direction, while speed does not

• Speed measures force, velocity does not

• Speed uses m/s, while velocity uses km/h

• Speed is constant, velocity always changes

If a car travels 120 km in 3 hours in a straight line, what is its average velocity?

• 40 km/h

• 30 km/h

• 120 km/h

• 360 km/h

An object moves 50 meters north in 5 seconds. What is its velocity?

• 10 m/s North

• 5 m/s North

• 10 m/s South

• 15 m/s South

Two cars travel at the same speed, but in opposite directions. What can you conclude about their velocities?

• They have the same velocity

• They have different velocities because of direction

• They have different speeds

• Their velocities are zero

What is the SI unit for acceleration?

• m/s

• m/s²

• km/h²

• N
