... When the fly hit the truck, it exerted a force on the truck (only for a fraction of a second). So, in this time period, the truck accelerated (backwards) up to some speed. After the fly was squashed, it no longer exerted a force, and the truck simply continued moving at constant speed. Follow-up: Wh ...

... move with a constant velocity. Since velocity is a vector, this means the speed (how fast) and the direction remain unchanged. Example: Take a look at a hockey game. When the puck (small black projectile) is hit, the puck travels at nearly the same speed and in a straight line across the ice. All re ...

From the point of view of someone standing near the conveyor belt, the graphite block falls straight down, lands with zero horizontal velocity, and is accelerated up to the speed of the belt. Fron a viewpoint on the belt, the block falls along a paraboli ...

Lesson 1: Newton`s First Law of Motion
... The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. In terms of an equation, the net force is equal to the product of the object's mass and i ...
