Why once we get an object moving does it require less force to keep it moving?
An object at rest stays at rest and an object in motion stays in motion at a constant speed and direction unless acted upon by an unbalanced force. In the absence of any forces, no force is required to keep an object moving.
What force is causing the objects to eventually stop moving?
Every day you see moving objects come to a stop. The force that brings nearly everything to a stop is friction,which is the force that acts to resist sliding between two touch- ing surfaces, as shown in Figure 3. Friction is why you never see objects moving with constant velocity unless a net force is applied.
How can we make this object move what causes the ball to move?
Force can make things move, change shape or change their speed. Some forces are direct and happen when two things touch (like a foot kicking a ball) or over a distance (such as a magnet or gravity). Friction is the force between two objects in contact with each other that will resist an attempt to move them.
Will the ball move by itself answer?
Answer: No! Explanation: Because In the first law of motion , an object will not change its motion unless a force acts on it.
Can a less massive object have more momentum than a more massive object?
A less massive object can never have more momentum than a more massive object. Two identical objects are moving in opposite directions at the same speed. The forward moving object will have the greatest momentum.
When the force on an object increases so does its?
From Newton’s second law the force on an object is related to the acceleration. The acceleration is directly proportional to the force applied to an object. For an object whose mass remains constant, when the force increases the acceleration increases. When the force on an object increases, so does its acceleration.
Does a stationary object have inertia?
Inertia is a force which keeps stationary objects at rest and moving objects in motion at constant velocity. Inertia is a force which brings all objects to a rest position. All objects have inertia. A more massive object has more inertia than a less massive object.
What is the momentum for an object at rest?
The momentum of any object that is at rest is 0. Objects at rest do not have momentum – they do not have any “mass in motion.” Both variables – mass and velocity – are important in comparing the momentum of two objects.
