While a body in motion cannot have zero average velocity, there are many examples where the average velocity - after selected intervals - is zero.
For example:
a pendulum, or any object under simple harmonic motion, after a complete number of cycles;
a rotating object (point on a wheel or hand of a clock) after a whole number of circuits.
Newton's first law of motion states that a body at rest remains at rest and a body in motion remains in motion at constant velocity in a straight line unless acted upon by an unbalanced force.
A body is said to possess kinetic energy when it is in motion. Kinetic energy is the energy an object has due to its motion and is dependent on both its mass and velocity.
Planetary velocity refers to the speed at which a planet moves along its orbit around the Sun or another celestial body. It is influenced by the planet's distance from the central body and governed by the laws of gravity and motion. The velocity of a planet is not constant throughout its orbit, as it changes based on its position and the gravitational forces acting upon it.
Kinetic energy is the energy an object possesses due to its motion. It depends on the object's mass and velocity, with the formula being KE = 0.5 * mass * velocity^2.
Yes, a body can have a nonzero average speed but zero average velocity if it moves around a closed path and returns to its starting point. For example, if a car travels around a circular track at a constant speed, its average speed will be nonzero (as distance is covered), but its average velocity over the entire trip will be zero as the displacement is zero.
Yes, but in uniform motion.
Yes, But in uniform motion only.
When the average velocity of a body is equal to its instantaneous velocity, it means that the body is moving at a constant speed in a straight line. This indicates that the body's motion is uniform, with no acceleration or deceleration occurring.
No, a body cannot move with a constant velocity in an accelerated motion. Accelerated motion implies a change in velocity over time, so the velocity of the body would not remain constant.
Both a body at rest and a body moving have a velocity of zero at a single point in time. The difference lies in their average velocities over a period of time - a body at rest maintains a constant velocity of zero, while a body in motion will have a non-zero average velocity over that period.
The measure of the motion of a body equal to the product of its mass and velocity is momentum. Momentum is a vector quantity that describes the motion of an object and is calculated as the product of the mass and velocity of the object.
The rate of directed motion of a body at an instant is referred to as its velocity. Velocity comprises both the speed of the body and its direction of motion. It is a vector quantity, indicating both the magnitude and direction of motion at a specific point in time.
A body experiencing uniform motion does not have any acceleration. Acceleration is the rate of change of velocity, and since the velocity of a body in uniform motion remains constant, there is no change in velocity and therefore no acceleration.
Yes, a body can be in motion but have zero acceleration if it is moving at a constant speed in a straight line. Acceleration measures the rate of change of velocity, so if velocity is constant, acceleration is zero even though the body is in motion.
If the force opposes the motion, it will reduce the velocity and the momentum of the body will decrease. If the force is in the direction of the motion, the velocity will increase and the momentum will increase.
The instantaneous velocity of a body is always in the direction of the resultant force acting on it at that instant. It is influenced by the net force and not necessarily by the least resistance or the current motion of the body.
It can be in equilibrium if in constant motion (constant velocity) as no forces are acting on it (no acceleration)
