Terminal Velocity

A skydiver jumps from a plane. The instant she jumps, the force(s) acting on her are

• Weight

• Weight and air resistance

• Weight and Friction

• Air resistance

A skydiver jumps from a plane. The instant she jumps, her resultant force is

• upwards

• to the right

• downwards

• to the left

A skydiver jumps from a plane. The instant she jumps, she is

• decelerating

• accelerating

• travelling at a constant speed

• stationary

A skydiver jumps from a plane. As she falls, air resistance upwards is

• decreasing

• increasing

• constant

• zero

A skydiver jumps from a plane. As she falls, the resultant force downwards (weight - air resistance) is

• decreasing

• increasing

• constant

• zero

A skydiver jumps from a plane. As she falls, the resultant force downwards decreasing, and her acceleration is

• decreasing

• increasing

• constant

• zero

A skydiver jumps from a plane. The air resistance has increased so it is equal in size to her weight. The resultant force acting on her is

• decreasing

• increasing

• constant

• zero

A skydiver jumps from a plane. The air resistance has increased so it is equal in size to her weight. The resultant force acting on her is zero so her acceleration is

• decreasing

• increasing

• constant

• zero

A skydiver jumps from a plane. The air resistance has increased so it is equal in size to her weight. She is

• accelerating

• travelling at terminal velocity

• stationary

• decelerating

The skydiver opens her parachute. The air resistance upwards

• increases

• decreases

• is zero

• remains constant
