No work is done on an object unless there is a force along its direction of motion This being so does the string that supports the pendulum bob do work on the bob as it swings to and fro?

Does weight have direction?
Yes. Weight is the amount of gravitational force on an object. So, it has the same direction as gravity.
What does space planetary wobble means?
Wobble refers to the rotary motion of an object - on a axis of any angle, has a lopsided or off-balenced hemisphere or side(or multiple sides). When this object is in motion it will move in an uneven fashion everytime this particular hemishere(s) travels around said axis. This is probably the true reason the Earth has tides in its oceans, due to "planitary wobble". kiss me you fool
How is momentum formed?
The equation for momentum is mass times velocity or P=mv It is formed my how massive an object is and how fast it is moving in any given direction.
If you jump up and down in a moving vehicle will you land in the same spot and why?
You will land in the same place relative to that vehicle, provided that vehicle is going at a constant speed in a constant direction. You can try this on a train. Make sure you try it when the train is not speeding up, slowing down, or going around a corner. Jump as high as you can, and you should land in basically the same spot on the floor of the train. But if you do it while looking out the window, you will see that you are still passing objects. This is because of inertia, described by Newton's first law. "An object in motion will remain in motion unless acted upon by a net force." So with no wind inside the train, and no-one pushing on you, you will land on the same spot on the floor of the train from which you jumped. Source: http://en.wikipedia.org/wiki/Law_of_inertia
What is a patteteg instruments?
[object Object]
When is an object said to in motion if it changes in time?
Pendulum
What happen to the speed of moving object when it is pushed in the direction of motion?
When a moving object is pushed in the direction of its motion the speed of the object increases
What happened to the speed of moving object when it is pushed in the direction of motion?
When a moving object is pushed in the direction of its motion the speed of the object increases
How does the direction of frictional force compare to the direction of an object motion?
The direction of the force of friction is such that it opposes the direction of motion that an object would move if there were no frictional force acting on the object.
What is a change in an object's motion called?
A change in speed or direction of motion is called "acceleration". If an object's speed or direction of motion changes, then the object is "accelerated".
What is the definition of speed of an object and specification of its direction of motion?
If the speed of an object is cited and its direction of motion is also cited, we have the velocity of the object. Velocity is speed plus a direction vector.
What happens to the speed of moving object when it is pushed in the direction of motion?
The speed increases. The object accellerates positively in the direction of motion.
What is the force that atcs in an opposite direction to the motion of a moving object?
Friction always acts in a direction opposing the motion of an object.
What direction does friction act in to an object's direction of motion?
Friction will always act in the direction opposite of the relativistic motion of two objects. If object A is moving to the right on object B, then object A will experience the friction to the left. However, object B will be moving to the left on object A and will therefore experience the friction acting towards the right.
How the direction of the force of kinetic friction is related to the direction of an object's motion?
Friction force works against the motion of the object. In other words friction force has the opponent direction of the velocity of the object.
What changes can a force produce in the motion of an object?
it is speed of motion and direction of motion
What the speed and the direction an object are moving?
If you know the speed and direction of the object's motion, then you know its velocity.
