Forces & Motion
Both
Force diagrams make direction marks easier.
Key Facts
- F = ma
- Acceleration changes velocity.
Key Equations
F = m × a
Speed = distance / time
Topics Covered
Resultant Force
What you need to know
- •Resultant force = sum of all forces.
- •Zero resultant means constant velocity.
Exam Tips
- Draw a force diagram before calculating.
Motion Graphs
What you need to know
- •Gradient of distance-time = speed.
- •Gradient of velocity-time = acceleration.
Exam Tips
- Use area under velocity-time graph for distance.
Key Terms
Resultant force
The overall force after combining all forces.
Acceleration
Rate of change of velocity.
