Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).

Front

What is the formula for force?

Back

The formula for force is F = ma, where F is force, m is mass, and a is acceleration.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as KE = 0.5 * m * v^2, where m is mass and v is velocity.

Front

How does mass affect inertia?

Back

The more mass an object has, the more inertia it has, making it harder to change its state of motion.

Front

What happens to an object's motion when a force is applied?

Back

When a force is applied to an object, it can cause the object to accelerate, decelerate, or change direction.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

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

Back

The unit of force in the SI system is the Newton (N).

Front

What is the effect of a vacuum on sound?

Back

Sound cannot travel through a vacuum because it requires a medium (solid, liquid, or gas) to propagate.

Front

What is the formula to calculate force when mass and acceleration are known?

Back

The formula is F = m * a, where F is force, m is mass, and a is acceleration.

Front

What is the significance of the heaviest car in a race regarding kinetic energy?

Back

The heaviest car will have the greatest kinetic energy when in motion, assuming all cars are moving at the same speed.
