What are the similarities between uniform and nonuniform motion?
Uniform and nonuniform motion both involve the movement of an object from one point to another. In uniform motion, the object travels at a constant speed in a straight line, while in nonuniform motion, the speed or direction of the object changes over time. Both types of motion can be described using mathematical equations that relate the position, velocity, and acceleration of the object. Additionally, both types of motion can be analyzed using principles of kinematics and dynamics in physics.
When is the velocity vector of a particle tangent to the path of the particle?
The velocity vector of a particle is tangent to the path of the particle at any point. This is because velocity is a vector that points in the direction of motion of the particle at that particular instant.
What is the measure of energy of motion of particle of matter?
The measure of energy of motion of a particle of matter is called kinetic energy. It is calculated using the formula KE = 0.5 * mass * velocity^2, where mass is the mass of the particle and velocity is its speed.
What is the speed of particles motion known as?
The speed of particle motion is known as velocity. Velocity is a vector quantity that specifies both the speed and direction of an object's motion.
What is the name given to the energy possessed by a particle due to its motion?
The energy possessed by a particle due to its motion is called kinetic energy. It depends on the mass of the particle and its velocity.
When a particle is in motion its velocity is always in the direction of motion?
This is true by definition. Motion is defined by difference in position occurring as a function of time, and "velocity" is is thethree-dimensional vector which quantifies that motion. To simplify the concept to a single dimension, if "x" is the position of a particle on a line at any instant of time, then the velocity of the particle is defined as dx/dt, that is, the change in position x divided by the change in time as the change in time approaches zero as a limit.
What is the approximate minimum stream velocity needed to keep a particle in motion that has a diameter of 10 centimeters?
The minimum stream velocity needed to keep a particle in motion can be estimated using the settling velocity equation. For a 10 cm diameter particle, the approximate minimum stream velocity would need to be around 0.03 m/s to keep it in motion. This value may vary depending on factors such as particle density and fluid properties.
What information can be inferred from Figure 1, the velocity-versus-time graph of a particle in simple harmonic motion?
From Figure 1, the velocity-versus-time graph of a particle in simple harmonic motion, we can infer the amplitude, period, and phase of the motion. The amplitude is the maximum velocity reached by the particle, the period is the time taken to complete one full cycle of motion, and the phase indicates the starting point of the motion within the cycle.
What is the net acceleration in a nonuniform circular motion?
The net acceleration in nonuniform circular motion has two components: the tangential acceleration, which is due to changes in speed along the circular path, and the radial acceleration, which points towards the center of the circle and is responsible for changing the direction of velocity. The net acceleration is the vector sum of these two components.
What is motion of particle without force?
A particle in motion without any external force acting on it will continue moving at a constant velocity in a straight line, following Newton's first law of motion. This motion will remain unchanged unless an external force is applied to alter its velocity or direction.
In the graph which region shows nonuniform positive acceleration?
A region with nonuniform positive acceleration on a velocity-time graph would appear as a curved or non-linear section where the velocity is increasing at a variable rate.
Can a particle in one dimensional with zero speed may have non zero velocity?
No, a particle in one dimension with zero speed will have zero velocity. Velocity is a vector quantity that includes both the speed and direction of motion, so if the speed is zero, the velocity will also be zero since there is no direction of motion.
