Acceleration is a change in the speed of an object (contrary to popular belief - acceleration ban be an increase or decrease in speed). Velocity of an object only changes when acted on by an external force like a push, friction or other force. Objects in motion stay in motion until acted on by an external force
What else can I help you with?
What is that which can cause an object with mass to change its velocity?
A force acting on the object can cause it to change its velocity. The force could be due to interactions such as pushing, pulling, gravity, or friction.
How do forces cause a change in an object's momentum?
A force acting on a body causes acceleration. Acceleration is measure of the rate of change in the object's velocity. As its velocity changes, its momentum, which is the product of its mass and velocity, will change.
What is a force that can cause an object to change its speed and direction?
A basic physics answer for this is that a net force (or unbalanced force) will cause an object to accelerate, that is, cause the object to change its speed and/or direction.
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.
How unbalanced forces change the velocity and acceleration of objects by completing the cause-and-effect graphic?
An unbalanced force causes a change in velocity by accelerating an object in the direction of the force. This acceleration is directly proportional to the magnitude of the force and inversely proportional to the mass of the object. In this cause-and-effect relationship, the force is the cause, leading to the effect of acceleration and a change in velocity of the object.
Can An unbalanced force cause an object to change its speed?
Yes, an unbalanced force can cause an object to change its speed by accelerating or decelerating it. When the net force acting on an object is not zero, it will cause a change in the object's velocity, which includes changes in speed.
How do forces cause an object to change its speed?
A forces on an object m creates an acceleration a=f/m and acceleration causes a change in velocity a= dv/dt. This change in velocity can change the speed or direction or both.
What will change if a force pushes an object in the same direction as the object's motion?
It will cause acceleration, and increase its velocity.
How do you calculate the change in velocity of an object?
To calculate the change in velocity of an object, you subtract the initial velocity from the final velocity. The formula is: Change in velocity Final velocity - Initial velocity.
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.
Rate of change of the velocity of an object?
The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".
Why is an object traveling at a constant speed but turning left said to be accelerating?
Acceleration is not a change in speed, but a change in velocity. Velocity is, unlike speed, a vector, and so as the direction of velocity changes there must be an acceleration to cause that change.
