Mastering GCSE Physics 🎓: Essential Equations Every Student Should Know 📚
GCSE Physics 101 🧪
Welcome to our guide on the must-know GCSE Physics equations! Whether you’re a student, parent, tutor, or teacher, understanding these fundamental equations can significantly boost your academic success in this vital subject. Let’s dive in!
The Key Players 🎭
1. Kinematic Equations 🏃♂️
- Equation 1: Distance (s) = Speed (v) x Time (t)
Example: If a car travels at 60 mph for 3 hours, how far does it travel? (Answer: 180 miles)
- Equation 2: Speed (v) = Distance (s) / Time (t)
Example: A ball is thrown horizontally at 25 m/s. If it takes 2 seconds to hit the ground, what is its height above the ground after 1 second? (Answer: 12.5 meters)
2. Force (F) = Mass (m) x Acceleration (a)
- Example: A 10 kg weight lifter accelerates at 5 m/s² while lifting a 20 kg weight. What force is he exerting on the weight? (Answer: 100 N)
The Energy Whiz ⚡
3. Energy (E) = Work (W) = Force (F) x Distance (s)
- Example: A worker pushes a box 10 meters along the floor with a force of 50 N. How much work is done? (Answer: 500 Joules)
4. Power (P) = Work (W) / Time (t)
- Example: A 75 Watt light bulb is on for 4 hours. How much energy does it use? (Answer: 300 Wh or 300 Joules)
The Motion Mavens 🚀
5. Momentum (p) = Mass (m) x Velocity (v)
- Example: A 2 kg ball moving at 10 m/s collides with a stationary 3 kg ball. What is their combined momentum? (Answer: 30 kg m/s)
6. Newton’s Laws of Motion 🌐
- Law 1: Inertia: An object at rest stays at rest and an object in motion stays in motion with the same speed and direction unless acted upon by an unbalanced force.
- Law 2: F=ma: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
- Law 3: Action and Reaction: For every action, there is an equal and opposite reaction.
