If the force acting upon an object are balanced then the object Amust not be moving Bmust be miving with constant velocity Cmust not be accelerating Dnone of these?
If the force acting upon an object are balanced then the object must not be accelerating
Is free fall balanced or unbalanced?
An object in free fall is accelerating, so the forces on it must be unbalanced.
Can an object be accelerating if it has constant velocity?
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
When an object floats the forces of weight and the force of upthrust are?
They must be equal. We know that, because if the vertical forces on the object didn't add up to zero, then it would be accelerating vertically, either up or down.
What to things must you specify when describing the velocity of an object?
The speed and the direction.
If an object is accelerating then the forces on it must be?
Friction force

If an object is not accelerating what can you determint about the sum of all the orces on the object?
In that case, the sum of all forces must be zero.
Does an object that has balanced forces or no force acting on it must be stationary?
No. An object that has no net force on it will simply not be accelerating. It can be in motion, but it can not have any change in its velocity.
Is free fall balanced or unbalanced?
An object in free fall is accelerating, so the forces on it must be unbalanced.
Can an object be accelerating if it has constant velocity?
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
If an object starts to accelerate?
If an object moved with constant acceleration it's velocity must ?
How does the weight of a floating object compared with the buoyant force acting on the object?
The weight of a floating object and the buoyant force on it must be equal. If they were not equal, then there would be a net vertical force on the object, and it would be accelerating up or down.
If an object is accelerating does Newton's third law apply?
Basically, Newton's Third Law ALWAYS applies.To accelerate an object, you need to apply some force to it. There MUST be a counterforce, from the object back to the object that pulls or pushes it.
When an object floats the forces of weight and the force of upthrust are?
They must be equal. We know that, because if the vertical forces on the object didn't add up to zero, then it would be accelerating vertically, either up or down.
How can you tell if an object is accelerating in a distance versus time graph?
The slope of the line of a distance versus time graph is the velocity of the object. If this is a constant, in other words the graph is a straight line, the object is not changing its velocity and so is not accelerating. If the object is accelerating, the velocity of the object will be changing, thus the graph will not be a straight line, but a curve - the amount of curvature (and direction) tells you how much the object is accelerating (and in what direction - velocity and acceleration are vector quantities with both magnitude and direction).
What two things must you know before finding the density of an object?
No
