What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What is the effect of gravity on an object in motion?

Back

Gravity pulls objects toward the Earth, causing them to change their velocity, which can result in acceleration or deceleration.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass and speed of the object.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a ball held at a height has gravitational potential energy.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What are nonmetals?

Back

Nonmetals are elements that are typically brittle, dull, and poor conductors of heat and electricity.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.

Front

What is the relationship between force and motion?

Back

A force applied to an object can change its motion, including its speed and direction.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 * mass (m) * velocity (v)^2.

Front

What is the formula for calculating potential energy?

Back

Potential energy (PE) = mass (m) * gravity (g) * height (h).
