Walker Physics Semester 1 Exam Review (Chs. 1-3)

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction of that line.

Front

What does a position-time graph plot on the y-axis?

Back

A position-time graph plots position on the y-axis.

Front

What does a position-time graph plot on the x-axis?

Back

A position-time graph plots time on the x-axis.

Front

What is constant acceleration?

Back

Constant acceleration is when an object's velocity changes by the same amount each second.

Front

What does a motion graph showing a straight line indicate?

Back

A straight line on a motion graph indicates that the object is moving at a constant speed.

Front

What is average velocity?

Back

Average velocity is the total displacement divided by the total time taken.

Front

How do you calculate displacement?

Back

Displacement can be calculated using the formula: Displacement = Final Position - Initial 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 free fall?

Back

Free fall is the motion of an object under the influence of gravitational force only, with no other forces acting on it.

Front

What is the formula for average speed?

Back

Average speed = Total Distance / Total Time.
