Define reference point and displacement
Reference point: a basis or standard for evaluation, assessment, or comparison; a criterion. Displacement: the action of moving something from its place or position.
100
Define speed and velocity
Speed: someone or something moves or operates or is able to move or operate. Velocity: the speed of something in a given direction.
100
Define acceleration
a vehicle's capacity to gain speed.
100
Define momentum
the quantity of motion of a moving body, measured as a product of its mass and velocity.
100
What is the difference between mass and weight?
Mass is the property of an object or mass that tends to maintain its current state of rest or motion. Weight is the force that is generated when the gravitational force of the earth acts upon an object or mass.
200
Define position and motion?
Position: a place where someone or something is located or has been put. Motion: the action or process of moving or being moved.
200
Define net force and inertia
Net force: net force is the overall force acting on an object Inertia: a tendency to do nothing or to remain unchanged.
200
Define circular motion
circular motion is a movement of an object along the circumference of a circle or rotation along a circular path
200
Define force pair
A force pair is the action-and-reaction pair of forces that constitute an interaction.
200
What is the difference between contact force and non contact force?
contact force is when two objects are in contact with each other it is called and non-contact force is when two objects are not in contact with
300
Define gravity and friction?
Gravity: the force that attracts a body towards the centre of the earth, or towards any other physical body having mass. Friction: the resistance that one surface or object encounters when moving over another.
300
Define unbalanced and balanced forces
Unbalanced force: In physics, tension is the pulling force exerted by a string, cable, chain, or similar solid object on another object Balanced force:Forces are balanced when the forces pushing (or pulling) an object in one direction are the same size as the forces acting in the opposite direction.
300
Define centripetal force
a force which acts on a body moving in a circular path and is directed towards the centre around which the body is moving.
300
Define the law of conservation of momentum
A principle stating that the total linear momentum of an isolated system remains constant regardless of changes within the system.
300
How are constant,instantaneous and average speed alike?
Both are velocity functions. Instantaneous velocity is the derivative of the
400
Define force, contact force and non-contact force?
Force: strength or energy as an attribute of physical action or movement. Contact force: point of contact between two objects, in contrast to body forces. Non-contact force: non-contact force is a force applied to an object by another body that is not in direct contact with it.
400
What is Newtons First Law?
a body remains at rest or in motion with a constant velocity unless acted upon by an external force
400
What is Newton's Second Law?
the rate of change of momentum is proportional to the imposed force and goes in the direction of the force
400
What is Newton's Third Law?
action and reaction are equal and opposite
400
What is the difference between balanced and unbalanced forces?
Balanced - 2 forces pushing or pulling on the same object that have exactly the same amount of force (creates net zero force) Unbalanced - 2 forces pushing or pulling on the same object that have different amount of force. The side with the most force move in that direction.
500
Define mass and weight
Mass: a large body of matter with no definite shape. Weight: a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.
500
Define constant, instantaneous and average speed?
constant, instantaneous and average speed: speed of an object is the magnitude of its velocity; it is thus a scalar quantity
500
What is the difference between circular motion and centripetal force?
The difference is mass.
500
newton's laws of motion definition
three fundamental laws of classical physics.
500
What is similar between all three of Newtons Laws?
They all include gravity.
