What is the acceleratipn of a body with uniform velocity and why?
The acceleratipn of a body with uniform velocity is zero. Acceleratipn is the time rate of change of velocity. If the velocity is uniform, then its time rate of change is zero.
Which property of a body cannot be changed if a force is applied to it?
Its chemical property.
When the body will possess non uniform velocity?
When the velocity changes. And the velocity will change when the forces on an object change. For instance, some types of friction forces change as a function of velocity.
Can there be acceleration in the body even when the body is not speeding up or slowing down?
Yes. Acceleration is change in velocity. Velocity is either change in speed or change in direction. If you fix the speed, change in direction can account for change in velocity, i.e. acceleration.
What does it mean for a body to have zero acceleration?
The velocity of the body does not change.
What is an object's momentum?
It's the mass of a object on its velocity (the velocity is a vector and as result of multiplication of a scalar (mass) on a vector (velocity) you get a vector (momentum). Intuitively, momentum is the property of a body which enables it to resist a force.
What is the definetion of inertia?
Fundamental physical property of a body to resist change in its state of motion or direction.
What is the property of body that resists any change in velocity?
The reluctance of a body to change its state of motion is termed inertia. The mass associated with this property is called its inertial mass, notably different from gravitational mass, which is responsible for objects with mass experiencing an attractive force between them. The inertial rest mass of an object is what gives it momentum.
What is the acceleratipn of a body with uniform velocity and why?
The acceleratipn of a body with uniform velocity is zero. Acceleratipn is the time rate of change of velocity. If the velocity is uniform, then its time rate of change is zero.
Can velocity of a body vary if direction of the body change?
no
What is the property of a body that reists any chang in velocity?
The property is Momentium. This is because it is the combination of mass and velocity. It is hard to change Momentium because velocity is the component that has to change as it is hard to lose mass.P=mvAlso if an object manages to change their momentium it is known as Inertia. Inertia can be caused by a force applied over time.The property is Momentium. This is because it is the combination of mass and velocity. It is hard to change Momentium because velocity is the component that has to change as it is hard to lose mass.P=mvAlso if an object manages to change their momentium it is known as Inertia. Inertia can be caused by a force applied over time.*THAT IS ALL WRONG!!!!!*MOMENTUM - MASS OF AN OBJECT MULTIPLIED BY ITS VELOCITY!!!* YOU CANT EVEN SPELL MOMENTUM !!!!THE CORRECT ANSWER IS......INERTIA

What happens to the velocity of a moving body if you change the speed at which the body is moving?
The velocity changes. called acceleration.
What is meant by the acceleration of a body?
the rate of change in the velocity of a body
What does it mean for a body to have zero acceleration?
The velocity of the body does not change.
