    Uniform Circular Motion Uniform Circulated Motion is defined as a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform‚ with constant angular rate of rotation (and constant speed)‚ or non-uniform with a changing rate of rotation. The rotation around a fixed axis of a three-dimensional body involves circular motion of its parts. The equations of motion describe the movement of the center of mass of a body. Physics‚ particularly Uniform

    will pass over a pulley at the table’s edge so that as the mass falls the cart will be accelerated over the table’s force. The cart will be released from rest and allowed to accelerate over a distance. Using a stopwatch‚ we determine how long it takes‚ for the cart to move through the distance. The results that our group gathered seem not accurate because of human error. Introduction: Newton ’s second law of motion pertains to the behavior of objects for which all existing forces are not balanced.

    Jetée. In the beginning of the film‚ the narrator is speaking of a man dying‚ and while the narrator is speaking images flash across screen at a faster rate to create tension‚ and this is known as accelerated editing. Accelerated editing is used quite frequently in the movie. Another scene with accelerated editing shows images of scientists giving a man a shot. As the scene progresses and the needle gets closer to his arm the photographs on the screen

    FRICTION Friction is necessary for walking due to the following reason‚ As per Newton’s third law of motion‚ (every action has an equal and opposite reaction) we can walk if and only if the ground we are walking on push our feet back with a force. Now‚ as per the third law the ground would definitely push our feet back but if we are walking on a perfectly smooth ground which has no friction our force would simply cancel out the force reverted by the ground and we would fall. If there was no
