IPC Final Exam Review Part 1

Front

What is net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration and direction of motion.

Front

What does it mean when a car is accelerating?

Back

A car is accelerating when it is increasing its speed or changing its direction. This is represented by a positive slope on a distance-time graph.

Front

What does it mean when a car is stationary?

Back

A car is stationary when it is not moving, which is represented by a horizontal line on a distance-time graph.

Front

What does it mean when a car is traveling at a constant speed?

Back

A car is traveling at a constant speed when it covers equal distances in equal intervals of time, represented by a straight line on a distance-time graph.

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction. This explains how rockets move forward by expelling gases backward.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up), negative (slowing down), or zero (constant speed).

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 a distance-time graph?

Back

A distance-time graph shows how the distance traveled by an object changes over time. The slope of the graph indicates the speed of the object.
