Different types of motion in physics
- Definition: speed of an object in a specific direction.
- The formula for velocity is v=d/t.
- An object's velocity is constant if the direction or speed doesn't change.
- The velocity will change if the direction or speed changes.
- There is also resultant velocity- the combined velocity of different objects in motion.
- Speed and velocity are NOT the same.
- Definition: A measure of how much the velocity changes in a certain amount of time.
- An object accelerates if its direction,speed, or both change.
- There is positive acceleration (increase in velocity) and negative acceleration (decrease in in velocity.)
- The faster the change in velocity is, the great acceleration there is.
- Definition: When a force causes an object to move in the direction that force is applied over a distance(or force) that stops the movement.
- The formulas for work is W=Fd.
- Work is measured in joules(J).
- If there is no movement over a distance the is no work.
- There is positive work- when motion and force are in the same direction and negative work- when motion and force are in opposite directions.
