Force Exam Review 2024

Front

What is the net force?

Back

The net force is the vector sum of all the forces acting on an object. It determines the object's acceleration and direction of motion.

Front

What is the formula to calculate the system mass of multiple objects?

Back

The system mass is calculated by adding the masses of all individual objects in the system.

Front

If the masses M1 and M2 are quadrupled, how does it affect the gravitational force of attraction?

Back

The new force of attraction will be sixteen times the original force.

Front

Does your weight change depending on the planet you are on?

Back

True, weight varies based on the gravitational pull of the planet.

Front

What happens to gravitational attraction when objects are farther apart?

Back

Gravitational attraction decreases as the distance between objects increases.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

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

Back

The unit of force is the Newton (N).

Front

How do you calculate weight?

Back

Weight is calculated using the formula: Weight = mass × gravitational acceleration (W = m × g).

Front

What is the relationship between mass and weight?

Back

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

Front

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

Back

Increasing the distance decreases the gravitational force between the two masses.
