Kinetic Energy & Forces

Front

What is inertia?

Back

Inertia is the property of an object to remain at rest or in uniform motion unless acted upon by an external force.

Front

What does it mean for an object to be at rest?

Back

An object is at rest when it is not moving and its position is not changing relative to a reference point.

Front

Define speed in terms of motion.

Back

Speed is the distance traveled by an object divided by the time taken to travel that distance.

What is the formula for average speed?

Back

Average speed is calculated as total distance divided by total time.

Front

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy is directly proportional to the mass of the object and the square of its velocity (KE = 1/2 mv^2).

What is mass in physics?

Back

Mass is the amount of matter in an object, typically measured in kilograms.

Front

How does force relate to motion?

Back

Force is any interaction that, when unopposed, will change the motion of an object.

Front

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

Back

The unit of force is the Newton (N).

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
