Front

Which car is accelerating?

Back

A car that rounds a curve at a constant speed

Front

What is the formula for calculating acceleration?

Back

a = (final velocity - initial velocity) / time

Front

What does Newton's 1st law state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net force.

Front

What is the difference between speed and velocity?

Back

Speed is the distance traveled per unit of time, while velocity includes direction.

Front

What is average speed?

Back

Total distance traveled divided by total time taken.

Front

What is the unit of acceleration?

Back

meters per second squared (m/s²)
