Front

What is the y-axis in a graph?

Back

The y-axis is the vertical line on a graph that represents the dependent variable, which is affected by the independent variable. For example, in a graph showing bacteria growth over time, the number of bacteria would be plotted on the y-axis.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It is highest when the object is moving the fastest.

Front

What is an elastic collision?

Back

An elastic collision is a type of collision where both momentum and kinetic energy are conserved. Objects bounce off each other without losing energy.

Front

How can you identify an object moving at a faster speed on a graph?

Back

On a distance-time graph, a steeper line indicates a faster speed. The line with the greatest slope represents the fastest moving object.

Front

What does a constant speed look like on a graph?

Back

A constant speed is represented by a straight line on a distance-time graph, indicating that the distance covered is consistent over time.

Front

What is the independent variable in a graph?

Back

The independent variable is the variable that is manipulated or changed in an experiment, typically plotted on the x-axis.

Front

What is the dependent variable in a graph?

Back

The dependent variable is the variable that is measured or observed in an experiment, typically plotted on the y-axis.

Front

What does a flat line on a distance-time graph indicate?

Back

A flat line indicates that the object is not moving; it is stationary.

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 velocity.

Front

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, both momentum and kinetic energy are conserved. In inelastic collisions, momentum is conserved, but kinetic energy is not.
