What forces act on falling objects?
Falling objects The weight of the object – this is a force acting downwards, caused by the Earth’s gravitational field acting on the object’s mass . Air resistance – this is a frictional force acting in the opposite direction to the movement of the object.
What force actually accelerates an object?
The net force on an object is the combined effect (the sum) of all the pushing and pulling forces actually acting on the object. If the forces pushing or pulling on an object are not balanced (a net force acts) then the object will accelerate in the direction of the net force.
What 3 forces act on a meteor?
(c) When the meteor enters the Earth’s atmosphere, three forces act on the meteor. Gravity and upthrust are two of these forces….

What are 4 types of force?
fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay.
Do forces always cause motion?
In a short answer, yes. Once you apply a force to an object, it will move. So yes, forces will always result in motion, unless there is another force exactly opposed to it.
What forces are acting on the asteroid?
As it turns out, the asteroid is being held together by cohesive forces called “van der Waals,” a force that has been predicted for some asteroids, but hasn’t been seen before now.
What are 3 examples of force?
Some examples of force are:
- Gravitational force.
- Electric force.
- Magnetic force.
- Nuclear force.
- Frictional force.
