What is the path of projectile in the absence of friction?
The path that the projectile follows is a parabola… If there is no force acting on an object, then it will continue moving at a constant speed in the same direction.
Can you identify the factors that affect the projectile motion?
FACTORS AFFECTING PROJECTILE MOTION There are three main factors that affect the trajectory of an object or body in flight: the projection angle, magnitude of projection velocity and height of projection.
What are the factors that affects the maximum horizontal distance of a projectile?
The horizontal distance depends on two factors: the horizontal speed (vox) and the time the projectile has been in the air. The horizontal distance is the product of these two quantities. The height of the projectile depends on the original vertical speed (voy) and the time that the projectile has been in the air.
What is the most important characteristic property of projectile motion?
Objects experiencing projectile motion have a constant velocity in the horizontal direction, and a constantly changing velocity in the vertical direction. The trajectory resulting from this combination always has the shape of a parabola.
What are 5 ways force can change motion?
Question: What are five ways a force can change motion? Answer: The action by a force can cause an object to move or speed up , to slow down , to stop, or to change direction.
Which factors does the inertia of rest depend on?
Inertia depends on density and mass. Inertia is directly proportional to mass and density of an object. More the mass of an object, more is the inertia of the body.
What determines the inertia of a body do all bodies have the same inertia?
Explanation: inertia is directly proportional to mass. Greater the mass, greater the inertia.
What affects the moment of inertia of a rotating system?
Indeed, the rotational inertia of an object depends on its mass. It also depends on the distribution of that mass relative to the axis of rotation. When a mass moves further from the axis of rotation it becomes increasingly more difficult to change the rotational velocity of the system.
Does moment of inertia depend on mass?
The moment of inertia depends not only on the object’s mass, but also the distribution of that mass in relation to the axis of rotation. This means that the moment of inertia is higher for objects where the mass is distributed a long way away from the axis of rotation.
What is the formula for calculating moment of inertia?
Generally, for uniform objects, the moment of inertia is calculated by taking the square of its distance from the axis of rotation (r2) and the product of its mass. Now, in the case of non-uniform objects, we can calculate the moment of inertia by taking the sum of individual point masses at each different radius.
What is unit of moment of inertia?
The unit of moment of inertia is a composite unit of measure. In the International System (SI), m is expressed in kilograms and r in metres, with I (moment of inertia) having the dimension kilogram-metre square.
What is the SI unit of radius of gyration?
meter
Does inertia depend on shape?
Analyzing rotational inertia Rotational inertia depends both on an object’s mass and how the mass is distributed relative to the axis of rotation. If two objects have the same shape but different mass, the heavier one will have a larger moment of inertia.
What happens when moment of inertia increases?
Moment of inertia is a calculation of the required force to rotate an object. By increasing the radius from the axis of rotation, the moment of inertia increases thus slowing down the speed of rotation.
Which of the following has the greatest inertia?
Question: Which object has the greatest inertia? Answer: (4) a 20.0-kg mass has the greatest inertia.
What is the formula of radius of gyration K?
Mechanics: Here radius of gyration about an axis of rotation is calculated using mass moment of inertia and its formula is given by relation, k=√IM(1) (1) k = I M This equation (1) is the radius of gyration formula for mass moment of inertia.
What is the formula of radius of gyration Mcq?
Explanation: The radius of gyration of a body about an axis is a distance such that its square multiplied by the area gives moment of inertia of the area about the given axis. The formula of radius of gyration is given as k2 = I/A.
What is the dimensional formula of radius of gyration?
So finally, the dimensional formula of the radius of gyration will be written as: [M0LT0]. The power of zero on the dimension of the mass and time shows that the mass and the time dimensions are zero for the radius of gyration. So, the correct answer is “Option C”.
