Forces are the only things that can change an object's speed or direction, if both you and the object are in appropriately chosen inertial reference frames.
If you or the object are in a non-inertial frame (or frames), then the object's speed and direction can change with no cause at all. It's like magic. This actually happens in everyday life, in subtle ways, owing to things like the earth's rotation and its revolution around the sun. The effects are small so you don't feel them, but if you watch for a long, long time, you can detect changes of speed and direction that are best explained by these causes that we do not easily perceive.

What are 4 effects of forces?
Its effect are:- Changes the of position object Changes the of direction object Changes the of dimension object Changes the of speed object -Thunder
How can velocity of a moving object change?
Well, Velocity is speed in a spefic direction so if it changes it direction it changes altogether. Sk8
How is motion different from speed?
Motion is when an object changes its direction. Speed is how fast something is moving. Hope that helps!!
If an object accelerates in the same direction in which it is moving how is its speed affected?
The speed of the object will increase.
What changes the direction of a force?
Force changes either the speed or the direction of motion, or both.

The speed of the object will increase.
What happen to the speed of moving object when it is pushed in the direction of motion?
When a moving object is pushed in the direction of its motion the speed of the object increases
What happened to the speed of moving object when it is pushed in the direction of motion?
When a moving object is pushed in the direction of its motion the speed of the object increases
Under what circumstances can an object moving with an constant speed (uniform magnitude oits velocity) have an acceleration?
When the direction changes. A simple case is an object moving in a circle, at constant speed.
What changes the direction of a force?
Force changes either the speed or the direction of motion, or both.
What the speed and the direction an object are moving?
If you know the speed and direction of the object's motion, then you know its velocity.
What describes an object and speed and direction?
As regards a moving object, we call the measure of the speed and direction it is moving its velocity.
What is the speed of an object moving on a particular direction?
The speed of an object moving in a particular direction is called the velocity and it's a vector, that is, it has magnitude and direction. Speed is the scalar part of velocity.
How are velocity and acceleration different?
acceleration is the increase of speed in a moving object. velocity is the speed and direction of a moving object.
