G9-SCI-L7 Motion

What is the primary difference between distance and displacement?

• Distance is the total path covered, while displacement is the shortest path between two points.
• Distance is always greater than displacement.
• Displacement can never be zero.
• Distance includes direction while displacement does not.

Which of the following best describes uniform motion?

• An object moving at varying speeds.
• An object covering equal distances in equal intervals of time.
• An object that is at rest.
• An object that changes direction frequently.

If an object travels 60 km north and then returns to its starting point, what is its displacement?

• 60 km north
• 0 km
• 120 km
• 30 km north

What is the SI unit of speed?

• Kilometers per hour
• Meters per second
• Centimeters per second
• Miles per hour

What does a distance-time graph represent?

• The speed of an object over time.
• The distance covered by an object at different times.
• The acceleration of an object.
• The direction of motion.

Which of the following statements about velocity is true?

• Velocity is speed with direction.
• Velocity is always constant.
• Velocity cannot be negative.
• Velocity is the same as distance.

What happens to the velocity of an object in uniform circular motion?

• It remains constant in magnitude and direction.
• It changes in magnitude but not in direction.
• It changes in both magnitude and direction.
• It remains constant in magnitude but changes direction.

What is acceleration?

• The rate of change of distance.
• The rate of change of velocity.
• The total distance covered in a time interval.
• The speed of an object.

In the equation v = u + at, what does 'u' represent?

• Final velocity
• Initial velocity
• Acceleration
• Time

What type of motion is described when an object moves in a straight line with changing speed?

• Uniform motion
• Non-uniform motion
• Circular motion
• Accelerated motion
