Force and Gravity

Front

What is the force that attracts two bodies towards each other?

Back

Gravity.

Front

What is the relationship between mass and gravitational force?

Back

The more mass an object has, the more gravitational force it exerts.

Front

What happens to the time it takes for an object to hit the ground if it has a larger surface area?

Back

It may take longer to hit the ground due to increased air resistance.

Front

If two objects have the same mass, which one will hit the ground first when dropped from the same height?

Back

They will hit the ground at the same time, assuming no air resistance.

Front

What is the effect of force applied to brakes in a moving vehicle?

Back

The greater the force applied, the shorter the distance the vehicle will travel before stopping.

Front

What is the term for the resistance an object encounters when moving through air?

Back

Air resistance or drag.

Front

How does mass affect the acceleration of an object when a force is applied?

Back

Greater mass results in less acceleration for the same applied force (Newton's second law: F=ma).

Front

What is the formula for calculating gravitational force between two objects?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².

Front

What is the difference between mass and weight?

Back

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