PSci Unit 8 Review- Motion

Front

What does Newton's Third Law of Motion state?

Back

For every action, there is an equal and opposite reaction.

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have magnitude only (e.g., speed), while vector quantities have both magnitude and direction (e.g., velocity).

Front

What is a Free Body Diagram?

Back

A graphical representation that shows all the forces acting on an object.

Front

What does Newton's Second Law of Motion describe?

Back

The relationship between force, mass, and acceleration, expressed as F=ma.

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g).

Front

What is constant velocity?

Back

When an object moves at a steady speed in a straight line without changing direction.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

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

Back

The slope represents the speed of the object.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (final velocity - initial velocity) / time.

Front

What is gravitational force?

Back

The attractive force between two masses, proportional to their masses and inversely proportional to the square of the distance between them.
