What else can I help you with?
The change in an object velocity?
The change in an object's velocity is determined by its acceleration. If the object's acceleration is positive, its velocity increases; if it is negative, the velocity decreases. The larger the acceleration, the quicker the change in velocity will be.
What would you apply in order to change an objects velocity?
force
What needs to be applied in order to change an objects velocity?
To change an object's velocity, you need to apply a force to it. The force will cause the object to accelerate, thus changing its velocity. The magnitude and direction of the force will determine the extent and direction of the velocity change.
What caused objects to change velocity?
A force, or several forces that don't add up to zero, acting on the object.
Why must a force be exerted on a object to change its velocity?
To overcome the objects inertia
Why must a force be exerted on an object to change velocity?
To overcome the objects inertia
Why does gravity change velocity?
Gravity changes velocity because it accelerates objects towards the Earth at a rate of 9.81 m/s^2. As objects fall, their velocity increases due to this gravitational acceleration. Conversely, when objects move against gravity, such as when thrown upwards, gravity decreases their velocity until they eventually stop and fall back down.
What must be present to change an objects velocity?
A non-zero net force on the body.
What causes an object's velocity to change?
A change in velocity is caused by a change in acceleration. Objects do not speed up, slow down, or change direction unless they are pushed in some way. The acceleration (a) of an object with mass (m) produced by a given force (F) may be calculated using the equation a = F/m.
What causes the change in velocity?
A change in velocity can be caused by forces acting on an object. These forces can be due to interactions with other objects, such as a push or a pull, or due to internal processes like propulsion systems. Changes in velocity can also occur due to changes in direction, such as when an object turns.
Why is momentum caused?
momentum is caused by inertia. all objects have inertia, which means if they are moving at a certain velocity or are at rest they will continue to move at that velocity or remain at rest unless acted on by a force. Objects of more mass have greater inertia, so the amount of momentum is equal to the product of an objects mass and the magnitude of its velocity.
A net force acting on an object changes the objects what?
Direction or shape
