An applied pressure affects the motion of one object. An used force deserve to be a push, pull, or dragging on one object.

You are watching: A force causing an object to start moving

The push have the right to come from straight contact, like once objects collide or indigenous a force ar like magnetism. The pull seems to only come from a ar at a distance, like gravity or magnetism. Dragging can happen when sliding things over the surface ar of another.

The action from a force can cause an object to relocate or speed up (accelerate), to slow down (decelerate), to stop, or to change direction. Because any change in velocity is considered acceleration, it deserve to be claimed that a pressure on an item results in the acceleration of one object.

Questions friend may have include:

How have the right to a pressure accelerate an object? How have the right to a force slow under an object? When have the right to a force cause an object to readjust directions?

## Applied force can cause acceleration

When a force acts on an object that is stationary or no moving, the force will reason the thing to move, detailed there room no other forces staying clear of that movement. If you throw a ball, you space pushing on it to start its movement. If friend drop an object, the pressure of gravity reasons it to move.

If an item is at first stationary, it speeds up when it starts come move. Acceleration is the change in velocity over a duration of time. The thing is going native v = 0 to some other speed or velocity.

Likewise, if an object is already moving and also a pressure is applied in the exact same direction, the object will rate up or accelerate. Because that example, a gust the wind have the right to speed increase a sailboat.

### Accelerates Until pressure Stops

As long as the force is used to a given object, it will to accelerate. When the force is withdrawn, the object will proceed to move at a consistent velocity, according to the legislation of Inertia.

## Applied force can cause deceleration

If an object is moving and there is an used force in the opposite direction the the motion, the object will decelerate or slow down. If you litter a round up at a provided velocity, it will slow-moving down together it travel upward due to the force of gravity. Likewise, an aircraft will reducerhigh if flying into a solid headwind.

A decelerating force can cause a relocating object come stop. This deserve to be seen once you use the brakes on her car.

## Applied force can cause change in direction

A force used at an edge to the direction of movement of things can cause it to readjust direction. A side wind will cause an aircraft to adjust its direction.

It is possible that the thing keeps going at the very same speed, if the force is applied perpendicular to the direction the motion. However the velocity the the the object changes. Speed is how rapid the object is going, if velocity is speed plus direction.

## Summary

A force is a push, pull, or dragging on an object that influence its motion. The push have the right to come from direct contact, like when objects collide or indigenous a force field. The pull appears to just come native a ar at a distance. The action from a force can cause things to accelerate, to decelerate, to prevent or to adjust direction.

Since any adjust in velocity is thought about acceleration, it deserve to be stated that a pressure on an object results in the acceleration of one object.
