- If an object falls freely, the resultant force acting on it is the force of gravity. It will make an object close to the Earth's surface accelerate at about 10 m/s2.
- We call the force of gravity weight, and the acceleration the acceleration due to gravity.
- The equation: F = m x a
- Where: F is the resultant force in newtons, N
- m is the mass in kilograms, kg
- a is the acceleration is m/s2.
- Becomes: W…
