Front

Which equation is used to calculate the gravitational field of an object?

Back

F_g = mg

Front

If an object's mass is 30 kg on Earth, what is its weight?

Back

300 N

Front

What equation would you use to find the final velocity of an object accelerating from rest?

Back

v_f = at + v_i

Front

In physics, weight is measured in what unit?

Back

Newtons

Front

What is the formula for weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g)

Front

What is the value of gravitational acceleration on Earth?

Back

Approximately 9.81 m/s²

Front

How does weight change when moving from Earth to the Moon?

Back

Weight decreases due to lower gravitational acceleration on the Moon.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object's mass.

Front

If an object weighs 19 N on the Moon, what is its mass?

Back

Mass = Weight / g (Moon) = 19 N / 1.62 m/s² ≈ 11.73 kg
