1.1.6 — Know that the following quantities are vectors: force, weight, velocity, acceleration, momentum, electric field strength and gravitational field strength
These quantities require direction:
- Force
- Weight (force due to gravity)
- Velocity
- Acceleration
- Momentum
- Electric field strength
- Gravitational field strength
Real-world example:
When two people push a car, the forces must be in the same direction to be effective. If they push at right angles, the car moves in a completely different direction — this is vector addition in real life.
