Speeding up quiz

15 Questions

Quiz Description

This quiz will be focusing on acceleration and velocity. In our day-to-day life, we experience cars in motion, when these cars tend to move at a faster rate as their motion proceeds, it is known as speeding up. In the course of taking this quiz, you will learn things like velocity, acceleration, instantaneous speed, and all the laws of motion. GCE, GCSE, and SAT exams are often set from this particular part of Physics as it is Mechanics with Newton's laws. Therefore taking the quiz will help you study and have a better view of speeding up in order to pass your upcoming exams.

Speeding up is the rate of change of velocity with time. In other words, it is defined as acceleration. Speeding up is governed by laws, known as Newton's laws of motion. There are 3 of these laws and they help us in the calculation of velocity, and acceleration when given a problem to solve. These laws can be summarized mathematically as 

V^2=U^2+at.................(1)

V2=U^2+2aS ...................(2)

S=Ut+1/2at^2 ..................(3)  

For an object in motion; Where V is the final speed of the object, U is the initial speed of the object, a is acceleration, t is the time of motion, and S is the distance covered throughout the motion

Quizzes here are meant to open your mind wider, and these Physics quizzes are very much technical and so require precision, and taking the quiz will help you get that.
Do not forget these are exam standard quizzes with options one to four with only one being correct.
Good Luck!

A child is playing on a slide. Which statement is NOT true?


Correct
  • 1:

Correct
  • 1:
      the tension is less than the weight
