Vector quantities Study guides, Class notes & Summaries

What is Newton's first law? 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 unbalanced force. What are scalar and vector quantities? Examples. Scalars are quantities that only have magnitude (or size), while vectors have both magnitude and direction. Scalar: time, area, volume, temperature, and mass. Vector: displacement, velocity, force, and acceleration. Difference between distance and disp...
