What is the definition of tension in a system of connected masses?

Back

Tension is the force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

What does it mean for a system to be in equilibrium?

Back

A system is in equilibrium when the net force acting on it is zero, resulting in no acceleration.

Front

How is gravitational potential energy calculated?

Back

Gravitational potential energy (PE) is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is the height above the reference point.

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

According to Newton's second law, 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 the principle of superposition in electric fields?

Back

The principle of superposition states that the total electric field created by multiple charges is the vector sum of the electric fields created by each charge individually.

Front

What is the formula for calculating the electric force between two charges?

Back

The electric force (F) between two charges is calculated using Coulomb's law: F = k * |q1 * q2| / r^2, where k is Coulomb's constant, q1 and q2 are the charges, and r is the distance between them.

Front

What is the significance of electric field lines?

Back

Electric field lines represent the direction and strength of an electric field; they point away from positive charges and toward negative charges.

Front

What is the definition of speed in physics?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

How do you determine the greatest speed from a distance-time graph?

Back

The greatest speed on a distance-time graph is indicated by the steepest slope of the line.

Front

What is the concept of net force?

Back

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