Gravity

Front

What is gravity?

Back

Gravity is the force of attraction between two or more masses.

Front

What happens to all falling objects if air resistance is not a factor?

Back

All falling objects accelerate towards Earth at the same rate.

Front

How does gravity affect the mass of a skyscraper?

Back

As more mass is added to a skyscraper, gravity pulls on the structure with more force.

Front

What is the normal force in relation to gravity?

Back

The normal force is the support force exerted by a surface that counteracts gravity's pull.

Front

What is a projectile?

Back

A projectile is an object that is being pulled by gravity while also having a sideways force applied to it.

Front

How does gravity affect projectiles?

Back

Gravity pulls equally on objects that are in free fall and projectiles.

Front

What is the relationship between mass and gravity?

Back

Gravity pulls with more force on objects with greater mass.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravity only, without any air resistance.

Front

What is the effect of air resistance on falling objects?

Back

Air resistance opposes the motion of falling objects, affecting their acceleration.

Front

How do architects consider gravity in building design?

Back

Architects calculate gravity's effect to ensure structures can withstand the force of gravity.
