Throwing an object straight up in the air is an example of a motion in which acceleration is in the direction of motion. After the object is released, the acceleration due to gravity acts downward, which is in the same direction as the motion of the object as it goes up and then comes back down.
Actually, an object being swung in circles on the end of a rope is an example of circular motion, not projectile motion. Projectile motion refers to the motion of an object that is launched into the air and then moves under the influence of gravity. Circular motion involves an object moving in a circular path around a fixed point.
The apparent motion of an object can vary depending on the motion of the observer. This is due to the concept of relative motion, where the perception of an object's movement is influenced by the observer's own motion. For example, if the observer is moving towards an object, the object may appear to move faster than if the observer is stationary.
Any motion where the object moves from place to place, e.g. someone riding a bike.
An example of retarded motion is when an object slows down as it moves against a resistive force, such as air resistance. A car coming to a stop after applying the brakes is an example of retarded motion.
Convection occurs when heat is transferred into an object through motion or movement; an example would be boiling water.
No, an object sliding along a horizontal table is not an example of projectile motion. Projectile motion occurs when an object is launched into the air and follows a curved trajectory under the influence of gravity. A sliding object on a horizontal surface does not follow a curved path in the air.
one law is anything that is in motion stays in motion unless an object stops it
No, it's the opposite. Projectile motion is when something is moving through the air. An example is when a baseball is thrown.
Friction can stop an object in motion eventually. Friction causes drag on the object's motion energy and slows the object down by transferring the energy from one type to another. When the energy which acted on the object to put the object in motion is fully transferred, the object's motion will stop in the direction the motion and friction are applied. An example of this type of friction is the brake on a car. Friction can, however cause the object to change the direction of motion and simply stop affecting the object afterward. An example of this type of friction is the bumper rail of a pool table.
the object that can perform two or more types of motion at the same time is called multiple motion.
Newton's three laws of motion are 1) The motion of an object is constant unless acted on by a force. example - an object in orbit. 2) The rate of change of motion of an object (acceleration) is directly proportional to the force acting on it. example - having a bigger or smaller engine in a car 3) For every action there is an equal and opposite reaction. example - rocket engine in space.
