U1S2 - Changes in Forces and Motion (2024)

What is acceleration?

• A change in motion caused by an unbalanced force; includes an increase in speed, decrease in speed, or change in direction

• A straight path that an object can move along

• A push or pull that can change the motion of an object

• A system that uses coordinates or stationary objects to establish position or to measure movement of a point in space
