Front

What is the force that draws all objects towards Earth?

Back

Gravity is the force that attracts two bodies towards each other, with Earth exerting a gravitational pull on objects near its surface.

Front

What is the formula to calculate the force of an object in free fall?

Back

The force (F) can be calculated using the formula F = m * g, where m is the mass of the object and g is the acceleration due to gravity (approximately 9.8 m/s²).

Front

Convert 2200 meters to kilometers.

Back

2200 m = 2.2 km.

Front

What is conduction in terms of heat transfer?

Back

Conduction is the process of heat transfer through direct contact between materials, where heat moves from the hotter object to the cooler one without the movement of the material itself.

Front

What is displacement in physics?

Back

Displacement is the shortest distance from the initial to the final position of an object, taking direction into account. It can be zero if the starting and ending points are the same.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.8 m/s².

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms, while weight is the force exerted by gravity on that mass, measured in newtons.

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 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.

Front

What is the formula for calculating speed?

Back

Speed is calculated using the formula: Speed = Distance / Time.
