How did changing the slope of the incline change your velocity and acceleration values?
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.
The change in an object velocity?
a change in a objects velocity is caused by a unbalanced force :)
What is change in the speed of an object?
A change in the velocity is produced by a force acting on the object. A change in velocity means a change in speed or direction (or both).
How does the centripetal force cause an object to change in motion?
Any net force will change an object's velocity. In the case of a centripetal force, it changes the direction of the movement, and therefore its velocity.
How velocity is related to pressure?
It has a relationship. There must be a change in velocity over a period of time to have/create a force. f=ma If there is no change in velocity, meaning the acceleration is zero, then there's no force i.e. f = (50kg)(0m/s^2) = 0 N or kg*m/s^2

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.
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.
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 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.

What are the forces in net force?
Any time an object's velocity changes (the object "accelerates"), that is due to a net force. Here are some examples: * A car speeds up. The force is exerted by the tires, on the road. * A car slows down. The force is exerted by the tires, on the road, or by air resistance. * A car moves in a curve (its velocity changes too, since it changes direction). The force is exerted by the tires, on the road. * A planet moves around the Sun. The velocity changes all the time, since the direction changes. The force is exerted by gravity. * A falling object speeds up. The force is exerted by gravity.
Are mass and velocity forces?
No!! Force is how much work is being exerted on an object. NOT how much grav. pull (mass) or how much its accelerating (velocity)!
