Physics Regents Review 1-03

Front

What is the formula for electric potential (V) in terms of energy (E) and charge (q)?

Back

V = E/q

Front

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

Back

The object continues moving with constant velocity.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N)

Front

What is the work done (W) when a force (F) is applied over a distance (d)?

Back

W = F × d

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the relationship between mass (m), acceleration (a), and force (F) according to Newton's second law?

Back

F = m × a

Front

What is the definition of kinetic energy (KE)?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the definition of potential energy (PE)?

Back

PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the difference between a scalar and a vector quantity?

Back

Scalar quantities have magnitude only, while vector quantities have both magnitude and direction.

Front

What is the formula for calculating gravitational force (F) between two masses (m1 and m2) at a distance (r)?

Back

F = G(m1*m2)/r², where G is the gravitational constant.
