What is the acceleration of a 1000 kg car that is being pushed by a 56N force?
5.6 cm/sec2
What would be the situation if mass were added to or lost from a system while a constant force was being applied to the system?
Since Force = Mass x Acceleration If force is held constant and one varies the mass then the acceleration will vary according to the equation: Acceleration = Force / Mass As a result, the acceleration is inversely proportional to the mass of the object. In other words, if one increases the mass of the object, the acceleration of the object will decrease proportionally. Similarly, if one decreases the mass of the object, the acceleration will increase proportionally.
What is the acceleration of an object if velocity remains constant?
velocity is the first derivative of motion, with acceleration being the second; if an object has a constant velocity, then it's acceleration is 0. This is easy to see from everyday life, when you are in a car, you only feel it jerk when you are accelerating but once you've reached your speed you feel nothing.
What formula would you use to find the acceleration of a 10 kg boulder being pushed by a force of 65 N what would the acceleration be?
F = M aa = F / M = 65 / 10 = 6.5 meters per second2
Can an object reverse its direction while maintaining a constant acceleration?
One answer to this is that all object are in motion all of the time relative to all other objects. With that said, in the context of permanent halt" the only way that an object can be perceived as "halted" is by another object with the same velocity.
A science book is being pushed across a table Can the book have a constant speed and a changing velocity?
It can have a constant speed, and a changing velocity, but it cannot have the two at the same time. Remember: Velocity = speed with a directional component.
If an object is being accelerated can its velocity be constant?
No. Acceleration is any change of velocity.But its speed can be constant.

What does it mean to say that mass ad weight are proportional to each other?
The weight of an object is its mass multiplied by acceleration due to gravity. If you assume that acceleration due to gravity is a constant then weight would be a constant multiple of mass and the two measures would be proportional. However, gravitational acceleration varies across the earth: depending on latitude and altitude, as well as the density of rocks underneath and other local geological features. So the assumption about it being a constant is not true.

When a box is being pushed across a floor what acts between the box and the floor?
kinetic friction
What is the acceleration of an object if velocity remains constant?

Can an object moving at a constant speed have acceleration?
Acceleration is defined as the change in velocity over a given time period. Velocity is a vector quantity: it includes speed and direction. That being said, you can accelerate an object without changing its speed by simply changing its direction. A body moving along the circumference of a circle its speed may remain a constant, but its velocity will not be a constant since its direction of motion continuously changes, since the velocity changes it has an acceleration.
What effect does an increase in an objects mass have on the accleration of the object if net force remains the same?
As net force is constant, from Force= mass *acceleration mass becomes inversely proportional to acceleration (net force being the constant between them) ..thus if mass increases, the acceleration decreases. ( mass= net force* 1/acceleration) so the objects slows down.
Why is the ball deccelerating on an inclined plane?
The acceleration due to gravity remains constant, regardless of incline. The fact that it is on an incline does not change the fact that it will remain constant, it will only change the component of that acceleration being applied to the ball.
What formula would you use to find the acceleration of a 10 kg boulder being pushed by a force of 65 N what would the acceleration be?
F = M aa = F / M = 65 / 10 = 6.5 meters per second2
What happens when force is decreased?
Assuming that mass stays constant, a decrease in force will result in a corresponding decrease in the acceleration of the object being acted upon by the force.
