What is objects at rest and objects in motion?
Objects at rest are stationary and not changing position, while objects in motion are in motion and changing position over time. The concept is a key part of Newton's Laws of Motion, where an object at rest stays at rest unless acted upon by an external force, and an object in motion continues in motion with the same speed and in the same direction unless acted upon by an external force.
Why is a particle in uniform circular motion not moving at a constant velocity?
No. Velocity has direction and magnitude. The magnitude can be constant, but if the body is in circular motion, the direction of the movement is constantly changing, which means that the velocity is constantly changing. Changing velocity means that the body is accelerating. In this case, because the motion of the body is always changing away from a straight line to cause it to go round the circle, the acceleration acts towards the centre of the circle.
How are force and motion part of your everyday life?
Force and motion are part of everyday life in various ways, such as when walking, driving a car, or even sitting still. Force is needed to accelerate or decelerate objects, while motion occurs when there is a change in an object's position relative to a reference point. Examples include pushing a door open (applying force) or riding a bike (experiencing motion).
What is the force that accompanies a moving part?
The force that accompanies a moving part is typically called kinetic friction. This force acts opposite to the direction of motion and arises due to the contact between the surfaces of the moving part and its surroundings. It resists the movement of the part and is proportional to the normal force pressing the surfaces together.
Who invented the words force and motion?
The words "force" and "motion" do not have a specific inventor since they have been part of the English language for centuries. However, Sir Isaac Newton is credited with describing the relationship between force and motion in his laws of motion.

What part of a force does work when the direction of the force and the direction of motion are not the same?
Force only takes place in the direction of the motion. It cannot be any other way. It could be argued that the action of a cars tyres on the road applies to your question. The car moves forward while the tyres push the earth in the opposite direction. However the tyres are the motion supplying the force and not the car moving in the opposite direction..
When you pull a sled through the snow why does only part of your force do work?
Answer 1 - This is because of friction. Answer 2- This is because the force you exert must be in the same direction as the objects motion. So the part pulling forward does work, when the force pulling upward does not.

Why is the work output less when a force is exerted at an angle than when the force is exerted parallel to the direction of motion?
Because only a part of force (see vector analysis) is being used to do the desired work.

How does the direction of the force between two positivily charged objects compare with that between two negatively charged objects?
the two particles would be attracted together. the force of the two particles would, for the most part, depend on coulombs law F=kq1q2/r2 but a general rule for the direction is that likes repel and dislikes attract. a negative sign in this equation is often misunderstood to mean a negative force, but for coulombs law a negative means it repels and positive means it is an attractive force.
What is the only part of an applied force that performs work on an object?
The component of the applied force that is parallel to the displacement of the object is the only part that performs work on the object. This is because work is defined as force multiplied by the displacement in the direction of the force.
What causes objects in motion to change directions?
when an passenger travells in the bus when the bus changes its direction the body lean to the opposite side of the direction as our lower portion which is not in contact with the bus and the upper part move at the other direction
What state in the us ALWAYS features part of newtons second law of motion?
Every state in the US features aspects of Newton's second law of motion, which states that force is equal to mass times acceleration. This law applies universally to all objects in motion, regardless of the specific location.
