Is It Possible For An Object To Be In Motion If No Net Force Is Acting On It? Acceleration is the change of velocity per unit time, so if there is no force, all we know is that the acceleration is zero. Therefore, the velocity is not changing. If the object was already moving, then
Is The Average Speed For An Object That Makes A Round-trip Motion Is Always 0? The average velocity of an object on a round-trip journey would be 0. The direction of the velocity vector is dependent upon two factors: the direction the object is moving and whether the object is speeding up or slowing down.
Is It Possible For A Car To Move At Constant Speed And Be Accelerating? The velocity vector is constant in magnitude but changing in direction. … For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the
Should You Explain In Classical Mechanics A Moving Body With Constant Speed Has No Force? Since speed is equal to the magnitude of the velocity vector, it will also be constant. Again, since the acceleration is the rate of change of velocity of a body with time, if the velocity is constant, the acceleration of
Is Velocity Constant In Free Fall? Freefall is a special case of motion with constant acceleration, because acceleration due to gravity is always constant and downward. This is true even when an object is thrown upward or has zero velocity. … Acceleration from gravity is always constant and downward, but the direction and magnitude of
Is Work Done The Same As Acceleration? The work done to accelerate an object over a frictionless surface is equal to the change in kinetic energy of the object. Kinetic energy can be used to perform work. What is work done the same as? Work done has the same units as energy – joules. This
What Does It Mean When Velocity Is Constant? Constant velocity means that the object in motion is moving in a straight line at a constant speed. … The velocity can be positive or negative, and is indicated by the sign of our slope. What is an example of constant velocity? Answer to Essential Question 2.3:
What Is Acceleration When Velocity Is Zero? Acceleration is the rate of change of velocity of an object with respect to the time over which this change occurs. It is possible to have a non-zero value of acceleration when the velocity of a body is zero. … At this point, the velocity of the ball
What Does A Zero Acceleration Mean? If there is zero acceleration, that means there is no net force on the object, or . What is an example of zero acceleration? No acceleration means no change in velocity. For example an apple thrown in space. … A photon has zero acceleration because it can’t be accelerated.
What Is The Acceleration If Velocity Is Zero? At the highest point, the velocity of the ball becomes zero, after which it starts to fall down. At this point, the velocity of the ball is zero yet its acceleration is equal to g=9.8m/s2. What is the acceleration of the particle when the velocity is 0?
