AP Physics forces

Front

What happens to the normal force as the angle of an incline increases?

Back

The normal force decreases.

Front

What is the formula to calculate the tension in a rope when an object is hanging motionless?

Back

Tension = Weight of the object / Number of ropes supporting it.

Front

How do you calculate the gravitational force of attraction between two masses?

Back

Use Newton's law of universal gravitation: F = G * (m1 * m2) / r^2, where G is the gravitational constant.

Front

If the gravitational force between two masses is F, what happens to the force if one mass is doubled and the distance remains the same?

Back

The gravitational force will double.

Front

What is the relationship between gravitational force and distance between two masses?

Back

Gravitational force is inversely proportional to the square of the distance between the masses.

Front

What is Newton's third law of motion?

Back

For every action, there is an equal and opposite reaction.

Front

How does the mass of an object affect the gravitational force it experiences?

Back

The gravitational force is directly proportional to the mass of the object.

Front

What is the value of the gravitational constant (G)?

Back

G = 6.674 × 10^-11 N(m/kg)^2.

Front

What is the effect of increasing the distance between two masses on the gravitational force?

Back

Increasing the distance decreases the gravitational force.

Front

How do you find the weight of an object on Earth?

Back

Weight = mass * gravitational acceleration (approximately 9.81 m/s^2 on Earth).
