Review Game: Kinematics 1D

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing total distance by total time.

Front

What does the slope of a position vs. time graph represent?

Back

The slope of a position vs. time graph represents velocity.

Front

If a car slows down from +32 m/s to +8 m/s in 4 s, what is the acceleration?

Back

The acceleration is -6 m/s².

Front

A dog runs with an initial speed of 7.5 m/s to a stop in 15 seconds. What is the dog's acceleration?

Back

The dog's acceleration is -0.5 m/s².

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

Define displacement.

Back

Displacement is the change in position of an object, measured as a straight line from the initial to the final position.

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.

Front

What is constant speed?

Back

Constant speed means that an object covers equal distances in equal intervals of time, regardless of how small those intervals are.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).
