... The earth pulls “downward” on the rock. The falling rock pulls “upward” on the earth (with the exact same amount of force). The force exerted on the cannonball is the same as the force exerted on the cannon. But the cannonball accerates more because of its much lower inertia (or mass). ...

... Inertia is the tendency of any object to resist any change in motion. This means that if the object is in equilibrium (at rest or constant velocity), it will require an unbalanced force to change its motion. In other words, once set in motion, an object does not seek to change its motion, and will c ...

... Arrows are used to represent the direction and strength of a force. The arrow points the same direction as the force and the relative length of the arrow represents the strength, or magnitude, of the force. Forces are measured in Newtons!
