... Which is more difficult to stop: A tractor-trailer truck barreling down the highway at 35 meters per second, or a small two-seater sports car traveling the same speed? You probably guessed that it takes more force to stop a large truck than a small car. In physics terms, we say that the truck has gr ...

... 1. When no force is exerted on an object, the acceleration of the object is 0. 2. Any isolated object, the object that do not interact with its surrounding, is either at rest or moving at a constant velocity. 3. Objects would like to keep its current state of motion, as long as there is no force tha ...

Free Fall - Cobb Learning
... • Consider an apple falling from a tree. We know that it starts at rest and gains speed as it falls, or accelerates. • Gravity causes the apple to accelerate downward and is said to be in free fall. Free fall: when an object is only affected by gravity – SI unit: m/s2 ( for acceleration due to gravi ...
