1.There must be a reference point (stationary object ) to describe the position of the given body. 2. The position of the given body must continuously change with time and with respect to the reference point.

What are the 5 muscle movements?
1) Flexion: bending a joint to decrease the angle between two bones or two body parts.2) Extension: straitening and extending of the joint to increase the angle between two bones or body parts.3) Abduction: Moving the body part away from the body.4) Adduction: moving the body part toward the mid-line of the body.5) Rotation: Moving the body part around its axis.
What are two characteristics of tornadoes?
Two characteristics of tornadoes are violently rotating winds and intense low pressure.
Why does friction resist motion?
A friction is a force that acts in the opposite direction of a moving body. It acts at the meeting of two different surfaces. So friction always resists motion.
Suppose a train car in moving down the track at 10ms hits another train car that is not moving explain how momentum is conserved after the collision?
Conservation of Momentum:The total momentum in a closed or isolated system remains constant. If the two trains are moving as one after the collision, and were the same mass M each, the total momentum before and after the collision would be the same, ccording to the law. Before the collision, the momentum (velocity times mass) was 10 x M units (one train) which must now be the same but applied to two trains (2M) moving as one body. The Conservation of Momentum rule, will tell you that the new moving body, being twice the mass, would be moving half the velocity to conserve the momentum from before the collision.
Two objects with the same velocity must be moving in the same?
They would be traveling at the same speed. Two objects moving with the same velocity must be moving in the same direction and at the same speed. The reason for this is because velocity is speed in a specified direction. Another way to say that is to say that velocity is speed with a direction vector. It is a physical quantity with magnitude and direction. Two objects moving with the same speed could be moving toward a head-on collision. Or they could be moving along convergent, divergent or skewed paths. Not so with two objects that have identical velocities. They are moving on the same or on parallel courses, and they are moving at the same speed.
Can a body at rest have an accleration?
acceleration is a relative quantity . state of rest or motion is also relative . if two body is in rest or moving with same velocity and having same acceleration then one is in state of rest with respect to other . suppose a person sitting in a train then he is in rest with respect to train but he is moving with the acceleration of train with respect to the ground.
How do you define a force?
It is an external effort in the form of push or pull, which tries to make the change in the state or direction of the body( body might be moving or at rest) . These are of two types balanced forces and unbalanced forces .

Can pets be allowed when moving to the states?
If you are moving from state to state there is no problem, but if you are bringing in a pet from another country it will have to go through a check up and customs. They may quarantine it for a week or two as well.

What is the characteristics of a state?
"The" state or "a" state? The two are different. A state is a geographic division within the U.S. It has it's own separate laws from the federal gov. The state is another name for the federal government.
Were Aristotle's predictions of heavenly motion quantitative or qualiative?
I. Aristotle's Theory of Motion • Two basic principles: I. No motion without a mover in contact with moving body. II. Distinction between: (a) Natural motion: mover is internal to moving body (b) Forced motion: mover is external to moving body
