Combined quiz on forces and their effects and speeding up

15 Questions

Quiz Description

In this quiz, we will be looking at forces and their effects and speeding up. This quiz will help you understand how forces cause motion, and this motion is usually through a particular distance. Forces are one of the very few important topics in Physics, and a very fertile one for the exam and test settings. So this quiz is a very good quiz if you want to have a very good mark or pass during your tests and exams.

Forces cause motion, stop motion, and change the direction of motion of a moving object. When a force is applied, an effect is speeding up the object, then Newton’s law is in play. Here, the Force is the product of mass and acceleration(which is the speed in a particular direction per unit time). Mathematically,
F=ma
Note that, speeding up simply means acceleration. 

In our quizzes, we test you to be up to the task, and for this quiz, students will be tested based on practical situations so for you to be familiar with the questions that could be asked in your exam or so, you have to take the quiz. Other Physics quizzes are available too.
Good luck!

The graph shows part of an urban car journey in terms of the distance the car has travelled in a certain time. The car engine produces the forward motion thrust force F1. Acting against this are the combined forces of (i) moving parts friction (including braking) and (ii) the drag from air resistance, giving a total force F2. In which time span is force F2 more than F1?
