Physics 💥

• Physical quantities measured by scientists fall into two categories: scalars and vectors
• Scalars are physical quantities that have magnitude (size) only, such as energy, temperature, mass, distance
• Vectors are measurements that have size (magnitude) and direction, like a displacement of 4 m North
• Speed is a scalar quantity where direction is not important
• Velocity is a vector quantity where direction is important
• Scalar quantities in Physics include: mass, distance, speed, rate of change of speed, time
• Vector quantities in Physics include: displacement, velocity, acceleration, force, weight
