This document contains answers to revision and practice exam questions for Module 1. The answers provided include numerical values for kinematic quantities like displacement, velocity, acceleration and force as well as multiple choice answers for conceptual questions.
The variables include acceleration (a), time (t), displacement (d), final velocity (vf), and initial velocity (vi). If values of three variables are known, then the others can be calculated using the equations. This page demonstrates the process with 20 sample problems and accompanying solutions.
1. A car travels a distance of 540km in 6 hours. Calculate the speed of the car. 2. John is a runner. He runs the 100m sprint in 20.0 s. Calculate the John’s speed. 3. Lauren walks 400 m in 125 s . Calculate Lauren’s average speed. 4. A mouse runs a distance of 2.0 metres in 16 seconds. Calculate the speed of the mouse. 5.
Find a vector in the direction of unit vector ˆv =. 1/3, √ 8/3. and a magnitude of 11. Solution: By definition, a unit vector has a length (magnitude) of 1. To check this condition for the given vector, we use the Pythagorean theorem to find its magnitude as |ˆv|= q (1/3)2+ ( √ 8/3)2= 1 As expected for a unit vector.
Revision for AQA Physics GCSE, including summary notes, exam questions by topic and videos for each module.
practice problem 1. I went for a walk one day. I walked north 6.0 km at 6.0 km/h and then west 10 km at 5.0 km/hr. (This problem is deceptively easy, so be careful. Begin each part by reviewing the appropriate physical definition.) Determine… the total distance of the entire trip. the total displacement of the entire trip.
