Great Big AP Exam Review Flashcard

Front

What is the coefficient of static friction?

Back

The coefficient of static friction is a dimensionless value that represents the ratio of the maximum static friction force between two surfaces to the normal force acting on them. It determines how much force is needed to start moving an object at rest.

Front

How do you calculate the coefficient of static friction?

Back

The coefficient of static friction (μs) can be calculated using the formula: μs = F/N, where F is the force required to start moving the object and N is the normal force.

Front

What is the formula for calculating velocity?

Back

Velocity (v) is calculated using the formula: v = d/t, where d is the distance traveled and t is the time taken.

Front

What are the SI units for velocity?

Back

The SI units for velocity are meters per second (m/s).

Front

What does a negative velocity indicate?

Back

A negative velocity indicates that an object is moving in the opposite direction to the defined positive direction.

Front

What is a motion map?

Back

A motion map is a visual representation of an object's motion, showing its position at various time intervals, often represented by dots or arrows.

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 gravitational force?

Back

Gravitational force is the attractive force between two masses, proportional to the product of their masses and inversely proportional to the square of the distance between their centers, described by Newton's law of universal gravitation.

Front

How does mass affect gravitational force?

Back

The gravitational force is directly proportional to the mass of the objects involved; if the mass of one object is halved, the gravitational force between them is also halved.

Front

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

Back

The slope of a distance-time graph represents the speed of the object; a steeper slope indicates a higher speed.
