To change the speed of an object, you need to apply a force to it. The magnitude of the force and the direction in which it is applied will determine how the speed changes. If the force is in the same direction as the motion, the object will accelerate; if the force opposes the motion, the object will decelerate.
What else can I help you with?
Does inertia change with speed?
Inertia is a measurement of the amount of energy needed either to start the object moving, or to slow down or stop its movement. This depends upon the mass (weight) of the object, but more particularly its change of speed. The greater the mass (weight) of the object the greater the amount of energy needed to move it and stop it.
If an object is moving at a constant speed in one direction what is needed to change the speed direction?
To change the speed or direction of an object moving at a constant speed, an external force is required. This force can come from a push, pull, or any other interaction that can accelerate or decelerate the object in a different direction.
What happensto the speed of an object if a unbalanced force acts on it?
Then the speed will change.Then the speed will change.Then the speed will change.Then the speed will change.
If the speed of an object does NOT change the object is traveling at a what?
It is travelling at a constant speed. This does not mean that there is no acceleration or that the direction of motion remains the same.
Does change in speed of an object always indicate a change in speed?
Yes, a change in speed of an object always indicates a change in speed. Speed is a scalar quantity that represents how fast an object is moving without specifying the direction, so any change in the speed of an object indicates that it is either speeding up or slowing down.
What is needed in order to cause an object at rest to move or an object in motion to change the direction and speed?
A force.
What is needed to cause the object at rest to move or an object in motion to change the direction or speed?
Force, which causes acceleration
What is needed in order to cause an object at rest to move or an object you motion to change its deirection or speed?
An unbalanced force.
What is needed in order to cause an object at rest to or an object in motion to change its direction or speed?
An outside force to act on it
How does the affect the speed of an object?
More intertia makes it so more energy is needed in order to change the speed.
