Untitled Presentation

The maximum speed an object reaches when falling through a fluid, where forces are balanced.

The initial speed of an object when it starts to fall.

The speed at which air resistance is zero.

The speed at which an object bounces back after hitting the ground.

Earth

Moon

Mars

Jupiter

Weight = mass x gravity

Weight = gravity / mass

Weight = mass / gravity

Weight = gravity x mass squared

It increases

It decreases

It remains the same

It disappears

Because air resistance becomes greater than the weight force

Because the weight force increases

Because gravity decreases

Because the parachute adds weight

Terminal velocity is reached when resistance equals accelerating force

Terminal velocity is the maximum speed an object can reach

Terminal velocity occurs only in water

Terminal velocity means the object stops moving

0.03 m/s²

3.0 m/s²

1.0 m/s²

0.3 m/s²

The initial steep increase in velocity

The flat section at maximum velocity

The sudden drop in velocity

The final constant low velocity

Increasing the mass of the object

Increasing the surface area of the object

Increasing the drag force

Decreasing the gravitational field strength
