When is an object said to have uniform velocity?
It isn't. Constant velocity? Uniform velocity across a group of objects?
A glider sailing across the sky at a steady speed and altitude an example of and unbalanced force?
No. A glider that is moving at a constant speed and in a constant direction is at a constant velocity. In other words it is not accelerating. Therefore, all forces on it must be balanced.
A block is dragged at constant velocity in a straight-line path across a level surface by a force of 6 N what is the force of friction between the block and the surface?
'Constant velocity' means constant speed and direction. If the speed of the block is constant along the level block, then the net force on it in the forward direction must be zero. (It isn't accelerating.) You're pulling it in the forward direction with a force of 6 N. So the force of friction in the opposite direction must also be 6 N, for a total of zero.
The velocity time graph of a ball moving on surface of floor is shown in figure calculate the force acting on ball if mass of floor is 20gram?
a ball rolled across a horizontal table moved at cont ant velocity why?
A man pushes a large box across a rough wooden floor. The box moves with constant velocity. What can be said about the forces acting on the box?
There is no unbalanced force acting on the box.
A force of 80.0 N is required to pull a 25.0kg block across a constant velocity on a smooth surface on earth What force is required to pull the same block across the surface of Jupiter?
That's a trick question, right? Jupiter has no surface.
When is an object said to have uniform velocity?
It isn't. Constant velocity? Uniform velocity across a group of objects?
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.
What is the first law of motion to the motion of an ice skater sliding across the ice st a constant velocity?
If the velocity is constant, it follows that the the sum of all forces on the ice skater is zero.
Force that opposes motion of surface as it moves across another surface?
the force that opposes the motion of two touching surfaces is velocity.
How do Kelvin-Helmholtz Instability form?
Usually where there is a velocity difference across the face of two fluids- such as wind blowing across the surface of the water.
If you slide a hockey puck across a frictionless ice rink these must be a horizontal force on it too keep it in the motion?
F=ma constant speed would mean 'a' acceleration is zero thus force zero. The puck would be in equilibrium, and the force would be zero at constant motion. Constant motion is constant velocity including the constant zero velocity.
What is the tightness across the surface of water caused by the polar molecules pulling on each other called?
AnswerIt is called surface tension.Erosion is the process of Weathering and transport of solids.
What is temperature of ocean at surface?
The temperature of the ocean at the surface is not constant across all oceans. For example, the Arctic Ocean will have a much colder surface temperature than the Pacific.
A glider sailing across the sky at a steady speed and altitude an example of and unbalanced force?
No. A glider that is moving at a constant speed and in a constant direction is at a constant velocity. In other words it is not accelerating. Therefore, all forces on it must be balanced.
If a graph shows time on the horizonal axis and speed on the vertical axis a straight horizontal line across the graph would indicate?
The straight horizontal line would indicate constant speed.(NOT constant velocity. The velocity could very well be changing, but the graphdoesn't tell you anything about the direction of the motion, only that the speedis constant.)
A block is dragged at constant velocity in a straight-line path across a level surface by a force of 6 N what is the force of friction between the block and the surface?
'Constant velocity' means constant speed and direction. If the speed of the block is constant along the level block, then the net force on it in the forward direction must be zero. (It isn't accelerating.) You're pulling it in the forward direction with a force of 6 N. So the force of friction in the opposite direction must also be 6 N, for a total of zero.
