Motion in two dimensions – projectile motion
... An object undergoing a projectile motion has two components, a horizontal and a vertical component. To make things easier, it is always convenient to treat the components separately. We can use the coordinate system such that the vertical component is along the y-axis and the horizontal component is ...

... What does this law tell us? • Objects in equilibrium do not accelerate. Static equilibrium (rest) and dynamic equilibrium (constant velocity) are both the result of an object with zero net force. • The only difference between rest and constant velocity is the reference frame.
