IB Physics HL 2023 Update Fundamental SI units - ANS-kilogram (kg), metre (m), second (s), ampere (amp), mole (mol), kelvin (K) Random error - ANS-An unpredictable and largely uncontrollable uncertainty. (Examples include human reaction time and other forms of human measurement.) (Random errors can be reduced by taking the average of repeated measurements.) Systematic error - ANS-An error that occurs on all measurements. (An example is a zero error on a scale.) (Systematic errors can ...

Question 1 Correct 5.00 points out of 5.00 A 0.200 kg dart is fired horizontally at a speed of 2.75 m / s when it hits a 0.700 kg block ofwood suspended by a string. The nose of the dart sticks into 0.00210 m the wood. Together the dart and block swing upwards from a height of 0.0500 m above a table to 0.128 m above the table. Which of the following is the average force the dart applies to the block during impact? Select one: a. 32.4 N b. 15.1 N c. 1.36 N d. 0.872 N Straighterl...

STEM Exam I Questions & Answers 2023/2024 When a space vehicle travels in a nearly circular orbit around Earth, is a force required to maintain is high speed? If the force of gravity were suddenly cut off, what type of path would the space vehicle follow? - ANSWER-The only force acting on the space vehicle is force of gravity. If the force of gravity was cut off, the vehicle would fly off in a straight line. If an object is moving, it continues to move without changing its speed, unless act...

Physical Science, Physics Definitions, Matric IEB Vector - a physical quantity that has both magnitude and direction Scalar - a physical quantity that has only magnitude Resultant vector - the single vector which has the same effect as the original vectors acting together Distance - the length of path travelled Displacement - change in position Speed - the rate of change of distance Velocity - the rate of change of displacement Acceleration - the rate of change of velocity Weight - ...

Grade 11 Physics definitions (IEB) scalar - ANS-A physical quantity that possesses magnitude only. vector - ANS-A physical quantity that possesses both magnitude and direction. resultant force - ANS-The single vector which has the same effect as the original vectors acting together. Normal Force (Fn) - ANS-The perpendicular force exerted by a surface on an object in contact with it. Weight (N) - ANS-The gravitational force that the Earth exerts on an object on or near its surface. Ne...
