Great Big AP Exam Review Flashcard

Front

What is the equation of motion for an object moving with a constant velocity?

Back

x = vt + x0, where v is the velocity, t is time, and x0 is the initial position.

Front

Define net force in the context of motion.

Back

Net force is the vector sum of all the forces acting on an object, determining its acceleration.

Front

What is the role of static friction in motion on a banked curve?

Back

Static friction helps prevent slipping and allows the vehicle to maintain its circular path.

Front

What does a negative velocity indicate about an object's motion?

Back

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

Front

Explain the concept of work in physics.

Back

Work is done when a force causes an object to move in the direction of the force, calculated as W = Fd cos(θ).

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

How does the horizontal component of the normal force affect a vehicle on a banked curve?

Back

It provides the necessary centripetal force to keep the vehicle moving in a circular path.

Front

What is the significance of the acceleration of an object?

Back

Acceleration indicates how quickly an object's velocity is changing, affecting its motion.

Front

Define kinetic energy and its formula.

Back

Kinetic energy is the energy of an object in motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What happens to the acceleration of an object when the net force acting on it is zero?

Back

If the net force is zero, the object either remains at rest or continues to move at a constant velocity.
