Front

What force opposes the motion of an object sliding down a surface?

Back

Friction

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What does the conservation of energy state?

Back

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

Front

What is the formula for gravitational potential energy?

Back

PE = mgh

Front

What is force?

Back

A push or pull on an object that can cause it to accelerate.

Front

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

Back

Newton (N)

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass (Weight = mass × gravity).

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv²
