Physics Chapter on Friction and Motion

It's the overall change in an object's position, considering both the distance traveled and the direction.

A scalar quantity, it describes the rate at which an object covers distance.

It's the rate at which an object changes its velocity.

A vector quantity describing the rate at which an object changes its position, including both its magnitude and direction.

The study of how objects move, focusing on their position, velocity, and acceleration without considering the forces causing the motion.

The acceleration that keeps an object moving in a circular path at a constant speed. It is always directed towards the center of the circle.

The force that acts towards the center of a circular path, causing an object to move in a circle.

The motion of an object moving in a circle with a constant speed.

The tendency of an object to resist changes in its motion. It's directly proportional to the object's mass. So, heavier objects have more inertia and are harder to get moving or stop.

The sum of all external forces acting on an object. It determines the object's acceleration, and can be zero if forces are balanced.

A push or pull on an object that can change its motion. It's a vector quantity, meaning it has both magnitude and direction.

The relationship between force, mass, and acceleration. It states that the net force on an object is equal to its mass times its acceleration.

This law explains that for every action, there is an equal and opposite reaction. Forces always come in pairs, acting on different objects.

A force that opposes an object's motion and acts in the opposite direction of movement. It's like a drag on the moving object.

The type of friction that prevents an object from moving when a force is applied. Think of it as the 'maximum force' the surface can hold before the object starts to move.

The type of friction that acts on a moving object, opposing its motion. It's like a force slowing the object down.

The equation that describes the force of friction. It depends on the coefficient of friction and the normal force acting on the object.

A value that depends on the types of surfaces in contact and is used to calculate the force of friction. It's a measure of how 'sticky' the surfaces are.

The state of an object where only the force of gravity acts upon it. This means no other forces, like air resistance, are affecting its motion.

The force that attracts objects with mass towards each other.

The force needed to stretch or compress a spring. It's directly proportional to the distance the spring is stretched or compressed.

A constant that describes how stiff a spring is. Larger values mean a stiffer spring, requiring more force to stretch or compress it.

A relationship where one variable increases as the other decreases, or vice versa. For example, as the distance between two objects increases, the gravitational force between them decreases.
