Physics Semester 1 Final Exam Review - long

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by a net external force.

Front

What does a position vs time graph represent?

Back

It shows the position of an object at different times, allowing us to analyze its motion.

Front

How can you determine if an object is speeding up from a position vs time graph?

Back

If the slope of the graph is increasing, the object is speeding up.

Front

What is the formula to calculate the area under a curve in a position vs time graph?

Back

Area = base x height, where base is the time interval and height is the position value.

Front

What type of energy is stored in an object due to its height above the ground?

Back

Gravitational potential energy.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the relationship between force, mass, and acceleration according to Newton's 2nd Law?

Back

F = ma, where F is force, m is mass, and a is acceleration.

Front

What does a flat line on a position vs time graph indicate?

Back

The object is at rest; its position is not changing over time.

Front

What is the significance of the slope in a position vs time graph?

Back

The slope represents the velocity of the object.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is energy of motion.
