Mastering Kinematics: Equations and Problem Solving in Motion

The video tutorial by Easy Engineering focuses on kinematics, a branch of mechanics that deals with the motion of objects without considering external forces. It introduces kinematic equations and demonstrates their application through solving problems related to horizontal motion, vertical motion, and projectile motion. The tutorial provides step-by-step solutions to these problems, helping learners understand how to apply the equations to real-world scenarios. The video concludes with a summary of the key points discussed.

What is kinematics primarily concerned with?

• The study of energy transformations

• The study of motion without considering forces

• The study of forces and their effects

• The study of heat and temperature

Which equation is used to calculate the distance traveled when initial velocity, time, and acceleration are known?

• d = v_i * t + 0.5 * a * t^2
