What you’ll practice

Name each physical quantity and keep its units consistent. Recalling an equation is one step in modeling a situation, rather than a substitute for identifying the applicable assumptions.

Where this helps

Connecting quantities and solving physics problems more fluently.

Before you start

Use this topic to practice math you have already learned. The examples show the available kinds of recall tasks; this is not a complete textbook chapter. Check the answer form and any stated conditions.

Try a few examples

Real practice. Real progress.

Acceleration a is constant over real elapsed time t and all signed quantities use one coordinate convention.

Choose the exact expression.

Show answer

The gravitational field g is uniform near Earth's surface, h is measured from a chosen zero-potential reference, and mass is nonnegative.

Choose the exact expression.

Show answer

The model is classical and nonrelativistic, with nonnegative mass. For momentum, v is velocity. For kinetic energy, v is speed.

Choose the exact expression.

Show answer
