SYNCHRONOUS QUIZ (Motion)

When is an object considered to be in motion?

I. When its position changes with respect to a point of reference.

II. When its distance changes with respect to a point of reference.

III. When its direction changes with respect to a point of reference.

• I and II only

• II and III only

• I and III only

• I, II, and III

What is the difference between speed and velocity?

• Speed involves distance, and velocity involves time and distance.
• Speed is a measure of motion, and velocity is a measure of distance.
• Speed involves distance divided by time, and velocity involves distance.
• Speed involves distance divided by time, and velocity involves speed as well as direction.

Which of the following provides information about velocity as well as speed?

• 20 km/h, north at 50 km/h
• 100 cm at 10 cm per minute
• 17 meters at 3 meters per second
• 900 kilometers at 110 kilometers per hour

A bicycle has an average speed of 2 m/s. What does this statement mean?

• In one second, it travels 1 meter.
• It takes 2 second to travel 1 meter.
• It can travel 4 meters in 2 seconds.
• It can travel 2 kilometers in one meter.

An athlete can run 9 kilometers in 1 hour. If the athlete runs at that same average speed for 30 minutes, how far will the athlete travel?

• 18 kilometers
• 4.5 kilometers
• 9 kilometers
• 3.3 kilometers

Which of the following is true about an object that travels 5 meters to the left, then 2 meters up, then another 5 meters to the right?

• The displacement of the object is equal to 12 meters.
• The displacement of the object is equal to 12 meters down.
• The total distance travelled by the object is equal to 12 meters down.
• The total distance travelled by the object is equal to 12 meters.

Which of the following is not accelerating?

• A stone whirled along circular path
• A car moving along a straight highway
• Typhoon Ondoy slowing down from 120km/h to 60km/h
• Elma Muros running the 100m dash from rest to finish line

A ball is at rest on the ground and there is nothing around it that may cause it to move. What can you say on the acceleration of the ball?

• High acceleration
• No acceleration
• Cannot be determined
• It depends.

A roller coaster starts its speed at 4 m/s. After 3 seconds, its speed id at 22 m/s. What is the average acceleration?

• 3.0 m/s2

• 4.5 m/s2

• 5.0 m/s2

• 6.0 m/s2

Which of the following is NOT true about the object moving with a constant speed?

• The object is not accelerating
• The speed of the object is equal to zero.
• The distance travelled by the object is increases uniformly.
• The speed of the object remains the same all throughout the travel.
