Physics Semester 1 Final alt.

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by a net external force.

Front

What is net torque?

Back

Net torque is the sum of all torques acting on an object, which determines the object's rotational motion.

Front

How can you identify an object speeding up on a position vs time graph?

Back

An object is speeding up if the slope of the position vs time graph is increasing.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, including direction.

Front

What factors affect frictional force?

Back

Frictional force depends on the nature of the surfaces in contact and the normal force acting between them.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is static equilibrium?

Back

Static equilibrium occurs when an object is at rest and the net force and net torque acting on it are both zero.

Front

What is dynamic equilibrium?

Back

Dynamic equilibrium occurs when an object is moving at a constant velocity and the net force acting on it is zero.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object moves, while velocity is a vector quantity that includes both speed and direction.

Front

What is the principle of conservation of energy?

Back

The total energy in a closed system remains constant; energy can neither be created nor destroyed, only transformed.
