Lesson 5 Flashcard Review

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass and speed of the object.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a ball held at a height has gravitational potential energy.

Front

How does speed affect kinetic energy?

Back

Kinetic energy increases with the square of the speed. This means that if the speed doubles, the kinetic energy increases by four times.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is speed.

Front

What is the independent variable in an experiment?

Back

The independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable.

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment, which changes in response to the independent variable.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy is directly proportional to mass. This means that if the mass of an object increases, its kinetic energy also increases if speed remains constant.

Front

What is the significance of Quadrant IV in a coordinate plane?

Back

Quadrant IV is where the x-coordinates are positive and the y-coordinates are negative. It is located in the bottom right section of the Cartesian plane.

Front

What is the formula for potential energy?

Back

The formula for gravitational potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
