CPS M3 L1 & L2 Review

Front

What is work in physics?

Back

Work is defined as the product of force and the distance over which it acts. It is measured in joules (J).

Front

What is an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle to the horizontal, which allows a force to be applied over a greater distance, reducing the amount of force needed to lift an object.

Front

What is a first class lever?

Back

A first class lever is a simple machine where the fulcrum is located between the effort and the load. An example is a seesaw.

Front

What is mechanical advantage?

Back

Mechanical advantage is a measure of how much a machine multiplies the input force, allowing a smaller force to lift a larger load.

Front

What is power in physics?

Back

Power is the rate at which work is done or energy is transferred, measured in watts (W).

Front

How does a pulley work?

Back

A pulley is a simple machine that uses a wheel and a rope to lift or lower loads, changing the direction of the force applied.

Front

What is the difference between work and power?

Back

Work is the total energy transferred by a force over a distance, while power is the rate at which that work is done.

Front

What is a second class lever?

Back

A second class lever is a simple machine where the load is between the fulcrum and the effort. An example is a wheelbarrow.

Front

What is a wedge?

Back

A wedge is a simple machine that consists of two inclined planes joined together, used to split or cut objects.

Front

What is a fixed pulley?

Back

A fixed pulley is a type of pulley that is anchored in place and does not move with the load, primarily changing the direction of the force applied.
