How does inertia work?
It is exactly the same as momentum and covered by Newton's first law of motion. Inertia is a way of expressing the force required to get an object to move from rest, or the force required to change the velocity or direction of an object in motion. Anything that has mass will have inertia - a "resistance to move or change velocity or direction of motion".
This is an object's change in motion per unit time in a specified direction?
The phrase "change in motion" is rather slippery.The size of the change in the object's position, per unit time, in a specifieddirection, is the component of its velocity in that direction.The size of the change in the object's velocity, per unit time, in a specifieddirection, is the component of its acceleration in that direction.
Is the direction of the acceleration is the same as the direction of motion of the object?
No. The direction of motion is obviously based on the direction it is moving. However the direction of acceleration is based on the direction of the forces acting on an object. If I throw a baseball to you, it is moving horizontally, from me to you, however it has the force of gravity pulling it downwards, so the acceleration would point downwards. (There's also a little air resistance which is slowing it down. Air resistance is a form of friction, and friction always opposes motion. Since it's moving forward, air resistance would pull it backwards. So the acceleration would actually be a small amount back as well as straight down.)
What describes the motion of an object where there is no change in speed or direction?
Equilibrium describes any state where the acceleration and net force are zero. This means that the velocity will not change.
What can a force do?
a force is something that you apply to an object- it can move-change shape-change direction-slow it down-make it faster
What the resistance of an object to a change in the speed or direction of its motion?
Inertia refers to the resistance of an object to a change in its speed or direction of motion. This property arises from the object's mass, where greater mass typically leads to greater inertia.
What is the Resistance in change of motion?
Resistance in change of motion refers to the force that opposes the movement of an object. This resistance can come from factors such as friction, air resistance, or the inertia of an object. It acts in the opposite direction of the applied force, making it harder for the object to accelerate or decelerate.
What is the resistance of an object to changes in its motion?
Inertia is the resistance of a object to change in its motion
What is the resistance of an object to changes its motion?
Inertia is the resistance of a object to change in its motion
What do we call an objects resistance in speed or direction?
The resistance to a change in velocity is called "inertia". It is related to the mass of an object.
How does friction cause the motion of an object to change?
Friction opposes the motion of an object by creating resistance when two surfaces are in contact. This resistance can cause the object to slow down, change direction, or come to a stop altogether, thereby altering its motion.
What is the is the measure of an object's resistance to a change in its rotational motion about an axis called?
The measure of an object's resistance to a change in its rotational motion about an axis is called inertia. It is similar to an object's resistance to a change in its linear motion, but it specifically refers to rotational motion. The greater an object's inertia, the more difficult it is to change its rotational motion.
What keeps moving objects going in their direction of motion?
An object in motion will stay in motion due to its inertia, which is the tendency of an object to maintain its current state of motion. In the absence of external forces, such as friction or air resistance, there is no reason for the object to slow down or change direction.
What is a change in an object's motion called?
A change in speed or direction of motion is called "acceleration". If an object's speed or direction of motion changes, then the object is "accelerated".
The resistance of an object to changes in its motion?
The resistance of an object to changes in its motion is known as inertia. Changes in an objects motion include changes in its speed and direction.
What is the inertia of motion?
Inertia of motion is the resistance mass has to motion. It also is the resistance in change in momentum. Momentum includes two things: velocity and direction. When an object changes its velocity, the momentum of the object resists the change. Also, when an object does change its velocity, its momentum is directly changed. In general, the inertia of motion is matter's unwillingness to change velocity or momentum.
What must be applied to an object to change its direction?
A force must be applied to an object in order to change its direction. By exerting a force at an angle to the object's initial direction of motion, the object will change its path and move in a different direction.
