Projectile Motion Physics Concepts

Scalar has magnitude only, while vector has magnitude and direction.

By finding the gradient of the graph.

<p>An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an external force.</p> Signup and view all the answers

<p>The rate of change of momentum of a body is proportional to the resultant force acting on it and occurs in the direction of that force.</p> Signup and view all the answers

<p>For every action, there is an equal and opposite reaction. When a body A exerts a force on body B, body B exerts an equal but opposite force on body A.</p> Signup and view all the answers

<p>A skydiver's vertical velocity initially increases at a constant rate due to acceleration from gravity. As air resistance increases, their vertical velocity eventually reaches a constant value.</p> Signup and view all the answers
