How can one determine the force exerted by an object based on its velocity?
The force exerted by an object can be determined based on its velocity by using the formula: force mass x acceleration. When an object is moving at a certain velocity, its acceleration can be calculated using the change in velocity over time. By multiplying the mass of the object by its acceleration, one can determine the force exerted.
What must applied in order to change an object's velocity?
force
What is the relationship between the velocity of an whirling object and the centripetal force that is exerted on it?
The velocity of a whirling object is directly proportional to the centripetal force exerted on it. As the object moves faster, the centripetal force required to keep it in circular motion increases. The equation for centripetal force is Fc = (mv^2)/r, where m is mass, v is velocity, and r is the radius of circular motion.
What is force exerted by?
Force is exerted by an object when it pushes or pulls on another object. It is a vector quantity that can cause a change in the motion or shape of an object. Force is described by its magnitude (strength) and 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.

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
When a force on an object increases how does the object acceleration change?
Changing the magnitude or direction of forces exerted on an object changes the net force (sum of all forces) exerted on the object. The net force exerted on an object is defined as mass times acceleration (F = ma), where mass, m, is constant. This means that when the net force exerted on the object changes in magnitude (or direction), its acceleration will also change in magnitude (or direction). In addition, acceleration is defined as the change in velocity, so when the magnitude (or direction) of acceleration changes, the magnitude (or direction) of velocity will also change.
An object moving at a constant velocity will?
... continue to do that, until a force is exerted on it.
How is Mass related to the difficulty of moving an object?
According to the momentum principle, the change in momentum of an object is equal to the net force acting on the object by the amount of time the force is acting on it. This is encapsulated in Newton's second law. mVf-mVo=F*t Where m is the mass, Vf is the final velocity (after applying a force over time t), Vo is the object's initial velocity (before applying the force), F is the net force being exerted on the object and t is the amount of time the force is exerted on the object. Rearrange this equation a little bit, and you'll see how mass is related to changing and object's velocity: Vf-Vo=(F*t)/m If you hold F and t constant then you'll see that the change in velocity (due to the force exerted over a time t) gets smaller as mass gets greater. Therefore, the greater the mass an object has, the harder it is to change it's velocity.
When the double force applied on the object then how does the pressure exerted on the object change?
When the double force applied on the object then the pressure exerted on the object will also be doubled.
What must applied in order to change an object's velocity?
force
How did changing the slope of the incline change your velocity and acceleration value?
changing the slope of the inclined plane changes the values for velocity because of the unbalanced external force exerted on the object increases the velocity.
When does a force change the velocity of an object?
If the object is in free-space, and any force applied over a period of time will change the velocity of an object. Force = mass * acceleration. Acceleration = velocity / time. Therefore, Force = mass * velocity/time.
