Vector and scalars - Study guides, Class notes & Summaries

Scalars Quantities that are fully described by a magnitude alone. Vectors Quantities that are fully described by both a magnitude and a direction. Distance Scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement Vector quantity that refers to "how far out of place an object is" it is the object's overall change in position. Speed Scalar quantity that refers to "how fast an object is moving." Velocity V...

AQA A Level Physics Mechanics Exam Questions With Correct Answers Difference between a scalar and a vector - answervector has magnitude (size) and direction, whereas scalar only has magnitude (size). Examples of scalars - answerspeed, mass, time, energy, power Examples of vectors - answerdisplacement, velocity, acceleration, force, weight Adding perpendicular vectors by calculation - answerdraw vectors as a right angled triangle use pythagoras' theorem to find magnitude of resultant ve...

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...
