What else can I help you with?
What are two things must you specify when describing the velocity of an object?
When describing the velocity of an object, you must specify both the speed (magnitude of the velocity) and the direction in which the object is moving.
What is needed to start an object moving.?
An external force is needed to start an object moving. This can be applied through pushing, pulling, or some other method that imparts kinetic energy to the object.
What to things must you specify when describing the velocity of an object?
When describing the velocity of an object, you must specify the speed (magnitude of velocity) and the direction in which the object is moving. Velocity is a vector quantity, meaning it has both magnitude and direction.
What are kinematic quantities?
Kinematic quantities are variables that describe the motion of an object without considering the forces that cause the motion. They include parameters such as position, velocity, acceleration, and time. These quantities help in analyzing and describing the motion of objects in a physics context.
What are the quantities related to speed?
Quantities related to speed include velocity, which specifies both the magnitude and direction of motion; acceleration, which is the rate of change of velocity; and distance, which measures how far an object has traveled. These quantities are important in describing and analyzing the motion of objects.

Why is less force neede needed to keep an object moving than to start the object in motion.?
The best, purest answer is: Because no force at all is required to keep a moving object moving.
What are kinematic quantities?
Kinematic quantities are variables that describe the motion of an object without considering the forces that cause the motion. They include parameters such as position, velocity, acceleration, and time. These quantities help in analyzing and describing the motion of objects in a physics context.
Is force always neede to keep an object moving?
Force is never needed to keep an object moving unless there is an opposite force trying to slow the object.
What are the quantities related to speed?
Quantities related to speed include velocity, which specifies both the magnitude and direction of motion; acceleration, which is the rate of change of velocity; and distance, which measures how far an object has traveled. These quantities are important in describing and analyzing the motion of objects.
What is the force needed to stop a moving object?
The force needed to stop a moving object is equal to the object's mass multiplied by its acceleration. This force is generated by applying a force in the opposite direction to the object's motion, causing it to decelerate until it comes to a complete stop.
What is the rate at which an object is moving at a given instant called?
speed if no direction is needed velocity if direction is needed
What do you have to do to an object to make it start moving and what is this called in science?
To make an object start moving, you need to apply a force to it. This is known as the principle of inertia, which is a fundamental concept in physics describing how an object at rest will remain at rest unless acted upon by an external force.
What are the example of vector quantity and their importance to daily life?
Examples of vector quantities include velocity, force, and acceleration. These are important in daily life because they describe the direction and magnitude of physical quantities, such as how fast a car is moving in a particular direction, or the force needed to lift an object. Understanding vector quantities helps in fields like engineering, physics, and navigation.
