Conceptual Physics - Field Forces Review

Front

What happens to the electric force (Fe) when the charge (q) decreases?

Back

Fe decreases.

Front

What is the formula to calculate weight (W) of an object?

Back

W = m * g, where m is mass and g is the acceleration due to gravity.

Front

If an object's weight is 900 N on Venus, what is its weight on Mars if g = 3.8 m/s²?

Back

380 N.

Front

What is the nature of electric force?

Back

Electric force can attract or repel.

Front

What is the nature of gravitational force?

Back

Gravitational force always attracts.

Front

What happens to the force of gravity (Fg) when mass increases?

Back

Fg increases.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

Front

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

Back

Newton (N).

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.8 m/s².

Front

How does distance affect electric force?

Back

Electric force decreases as the distance between charges increases.
