CP- Motion Unit Review

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is measured in meters per second squared (m/s²).

Front

How do you calculate acceleration?

Back

The formula for calculating acceleration is a = (v2 - v1) / t, where v2 is the final velocity, v1 is the initial velocity, and t is the time taken.

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 does a velocity vs. time graph represent?

Back

A velocity vs. time graph shows how the velocity of an object changes over time. The slope of the graph represents acceleration.

Front

What does a horizontal line on a velocity vs. time graph indicate?

Back

A horizontal line indicates that the object is moving at a constant velocity, meaning there is zero acceleration.

Front

What is the unit of speed?

Back

The unit of speed is meters per second (m/s) or kilometers per hour (km/h).

Front

What is the formula for calculating distance?

Back

The formula for calculating distance is d = v x t, where d is distance, v is velocity, and t is time.

Front

What does it mean for an object to have constant velocity?

Back

An object with constant velocity is moving at the same speed in the same direction, which means it has zero acceleration.

Front

What is the significance of a slope on a distance vs. time graph?

Back

The slope of a distance vs. time graph represents the speed of the object. A steeper slope indicates a higher speed.

Front

What is the relationship between acceleration and velocity?

Back

Acceleration is the change in velocity over time. If an object’s velocity increases, it has positive acceleration; if it decreases, it has negative acceleration.
