Projectile Motion
Does the horizontal component or vertical component of a projectile stay constant?
The horizontal component does.
What is displacement?
The distance from the origin.
What method is typically used to solve physics questions with angles to it?
Component Method.
In what direction does friction act in for a moving object?
Friction will act in the opposite direction to the direction that the object is moving in.
Momentum and energy is always ___________.
conserved.
In order for the trajectory of a projectile to be symmetrical, what is the only acceleration that's supposed to be acting on it?
The acceleration due to gravity.
What can you get from the area and slope in a Velocity-Time Graph?
