Gravity

What happens when a 5-gram nickel and a 2-gram penny are dropped simultaneously from the same height?

• The nickel hits the ground first.

• The penny hits the ground first.

• Both hit the ground at approximately the same time.

• The penny floats down slowly.

Why does a flat piece of paper fall slower than a crumpled piece of the same paper when dropped from the same height?

• The flat paper has less mass.

• The crumpled paper is heavier.

• The flat paper experiences more air resistance.

• The crumpled paper is more aerodynamic.

What was the outcome when an astronaut dropped a feather and a hammer simultaneously on the Moon's surface?

• The hammer hit the surface first.

• The feather floated away.

• Both hit the surface at the same time.

• The feather hit the surface first.

When a heavy object and a light object are dropped from the same height simultaneously, which one hits the ground first (assuming no air resistance)?

• The heavy object

• The light object

• They hit at the same time

• It depends on the shape of the objects

When a 5-gram nickel and an 1800-gram steel ball are dropped simultaneously from the same height, which object hits the ground first?

• The nickel.

• The steel ball.

• Both hit the ground at approximately the same time.

• The steel ball floats down slowly.

A dart is shot horizontally from a toy gun, and another identical dart is simultaneously dropped from the same height. Which dart hits the ground first?

• The dart shot horizontally

• The dart dropped vertically

• They hit at the same time

• It depends on the initial horizontal velocity

What is the key reason why objects of different masses fall at the same rate (neglecting air resistance)?

• Heavier objects experience less air resistance.

• Lighter objects are naturally attracted to the Earth more strongly.

• The gravitational force on an object is directly proportional to its mass, and this mass also determines its inertia.

• All objects have the same gravitational mass regardless of their size.

When an object is launched horizontally, how does gravity affect its motion?

• Gravity only affects the horizontal motion, causing it to slow down.

• Gravity only affects the vertical motion, causing it to accelerate downwards.

• Gravity affects both horizontal and vertical motion equally.

• Gravity has no effect on horizontally launched objects until their horizontal velocity drops to zero.
