Science - Simple Machines/movement

A lever is a simple machine consisting of a rigid bar that pivots about a fixed point, used to move an object at a second point by applying a force at a third point. This mechanical advantage allows for easier movement of heavy objects.

A screw is a type of fastener that is commonly used for joining objects together. It has a helical ridge, known as threads, that wrap around the shaft of the screw. This design allows the screw to be easily driven into wood or other materials by rotating it with a screwdriver. Nails, bolts, and rivets are also fasteners but differ in their design and application.

A wedge is a simple machine consisting of two inclined planes meeting at a point. It is commonly used for splitting objects apart with a pounding force.

A pulley is a simple machine that consists of a wheel with a groove around its circumference and a rope or chain that runs along the groove. When one end of the line is pulled, the weight at the other end is raised. This makes pulleys useful in lifting heavy objects with less effort.

The wheel and axle is a simple machine that consists of a larger wheel (the wheel) connected to a smaller cylinder (the axle). These two parts are fastened together so that when one turns, the other also turns. This simple machine is used in various objects like cars, bikes, and door knobs.

A simple machine is a mechanical device that changes the direction or magnitude of a force. In the case of altering the effort and distance involved in doing work, an inclined plane is used to reduce the amount of force needed to move an object to a higher or lower level. While levers, pulleys, and screws are all types of simple machines, they serve different purposes in terms of mechanical advantage.

The correct answer is 'Push'. Pushing involves applying force against something to move it away, while the other options do not specifically describe this action.

The correct term for drawing or tugging at with force is 'pull', which involves applying force in a direction towards oneself.

The correct term for causing something to move around on an axis or about a center is to 'turn'. While the other options may involve some form of movement, they do not specifically refer to the action described in the question.

The correct term for causing something to turn around rapidly is 'Spin', as in spinning a coin on a table.

The correct word that describes springing back from a surface in a lively manner is 'bounce', as seen in the example sentence provided.

The correct verb that describes the action of moving to and fro or up and down quickly and repeatedly is 'vibrate'. The other options may have similar meanings but do not precisely match the description given in the question.

The correct term for this action is 'roll' which involves the movement of an object by revolving or turning over and over.

Beside is the correct term used to indicate being by or at the side of something. Besides means in addition to or apart from, and Beyond means further away or outside of the specified area.

The correct word that fits the description of 'In, at, or to a higher place' is 'Above', as it indicates a position higher in space or at a higher level.

The correct term for the support or point of rest on which a lever moves is known as the fulcrum. This is a key concept in understanding how levers work in physics.

Gears are mechanical devices used to transmit motion between rotating shafts. Sprockets, pulleys, and cogs are similar components, but they serve different purposes and may not always have teeth for direct engagement.
