When an object is moving, it demonstrates a change in its position with respect to a reference point over time. This change in position can be observed through its displacement, velocity, and acceleration relative to the reference point.
rate of change of displacement is known as velocity it shows that how fast or slow a body is moving and in which direction it is moving.
this object that appears to stay in place is a reference point.
Velocity is negative in a moving object when the object is moving in the opposite direction of its positive reference point.
it means an object is moving based on the force of friction and gravity.
Kinetic energy
The object moving directly towards earth
Precision shows how well the object is moving.
The speedometer shows how fast a vehicle is travelling. It begins with the letter s.
rate of change of displacement is known as velocity it shows that how fast or slow a body is moving and in which direction it is moving.
this object that appears to stay in place is a reference point.
The red shift shows the velocity with which an object is moving away from the earth. The red shift of an object is correlated to its distance from the earth and so it is also a measure of the distance.
Velocity is negative in a moving object when the object is moving in the opposite direction of its positive reference point.
the force or other moving object
Laser sensor gives positive displacement as the object moves away and negative a the object is moving near. In fact the analog voltage output if analysed, shows that the laser gives higher voltage when target object is far from the sensor and higher if it is near.
it means an object is moving based on the force of friction and gravity.
Kinetic energy
The friction of a non-moving object is called static friction. It is the force that prevents the object from moving when a force is applied to it.
