Kinematic equations - Study guides, Class notes & Summaries

This Grade 12 IEB Physical Science summary on kinematics provides detailed explanations and equations of motion, including displacement, velocity, and acceleration. It covers the key equations for uniform acceleration, interpreting motion graphs, and calculating areas under velocity-time and acceleration-time graphs. Ideal for exam preparation, this guide gives students a strong grasp of kinematic principles.

Given density, what is the method to find molarity? Correct Answer: p = m/v ... solve for m ... find mol by multiplying m x mol/m (molar mass which should be given)... plug in mol into M = mol / L of solution! What are the properties of a water molecule? Correct Answer: The bent structure of the water molecule and ratio of covalently-bonded hydrogens to lone pairs of electrons on the oxygen atom maximizes the hydrogen bonding that occurs in the solid phase, producing a hexagonal structure w...
