Motion and time

What is the proper definition of motion

• when an object immediately stops

• when an object moves randomly

• when an object changes position over time

• when an object gets destroyed by something

There are 4 types of motion listed here and one of them is wrong, choose the INCORRECT one.

• Rectilinear Motion

• Oscillatory Motion

• Altruistic Motion

• Curvilinear motion

What is a frequency?

• amount of time it takes per oscillation

• Amount of oscillations per second

• Amount of seconds for 10 oscillations

• amount of seconds per frequency per single oscillations

Answer explanation

ok, so a frequency is just the number of oscillations per second, that's all you really need to know, a time period is the time for an oscillation, the answer was in the photo.

what is the unit for speed?

• Ac

• ds/fr

• k/y/s

• km/h

What is the formula for speed?

• temperature per distance

• time per time

• time per distance

• time per distance per acceleration per velocity per gravity per force per temperature per time per time per distance

now tell me the speed of the car if it travels for 5 hours for 495 kilometers?, type the answer in this way{the shown example isn't the answer don't try it(don't use caps please)} = 54 km/h

Answer explanation

formula for speed is distance/time, thus 495/5 = 99,

so the answer is 99 km/h

Some friends decided to check how long they could run in a very long track, who is the one who is running in uniform motion?

• Binod

• Kanye

• Rick

• Jake

• Siri

Challenge: Who is running in regular intervals?

• Blue guy

• Red guy

• I really don't know?

Challenge: which of these are more faster then 15km/h

• 7km/h

• 5cm/h

• 25km/h

• 28000000cm/h

• 1mm/h

If it takes 10 seconds for it to reach point a to point b then how long will it take to complete 7 oscillations?(2 minutes are given for this question)

• 560 seconds

• 280 seconds

• 140 seconds

• 210 seconds

• 420 seconds

Answer explanation

point a to point b takes 10 seconds, for one oscillation it should travel from point a to point b, then to point c then goes back to point b then finally reaches its initial position(here point a), so 4x10 = 40, next 7 oscillations so it will take 40x7 or 280 seconds
