Opposite Tom's home is a hill. Tom climbed slowly up the hill, walked across the top, and then ran quickly down the other side.
Tom walked home then he stopped and waited to watch the sky. After that, he ran to get home .
Tom was walking to the park. He stopped and waited so the baby chicks could pass.

Just after she jumps out of the plane (before the parachute opens). The net force will be
zero
upward
downward
After the 60 seconds, the parachutist pulls the cord and opens her parachute.
Explain how the parachute reduces the speed of the parachutist when it is just opened.
The friction force decreases
The weight force decreases
The weight force increases
The friction force increases
When a parachute canopy is opened more drag is created because:
It has a large mass
It has a large surface area
It is travelling at terminal speed
The person is now vertical
Identify true statements:
The parachutist has just left the plane
Weight is increasing
There is no drag
Weight is constant
Deceleration
The graph shows the vertical speed of a parachutist. At which point did they open the parachute?
A
B
C
D
John, of 68kg dives out of an aeroplane
a) What is John's weight
b) What happens to John's weight as he falls?
a) 0.68N
b) stays the same
a) 680N
b) stays the same
a) 680N
b) increases
a) 0.68N
b) decreases
When a skydiver is falling what happens to
a) her velocity
b) the air resistance?
a) Increases
b) increases
a) increases
b) decreases
a) increases
b) stays the same
a) stays the same
b) increases
Explain why the skydiver will eventually stop accelerating
The air resistance continues to increase as long as the velocity increases. When the air resistance reaches the same value as the weight there will be no resultant force, hence no acceleration (F=ma)
The air resistance continues to decrease as long as the velocity increases. When the air resistance is larger than the weight there will be no resultant force, hence no acceleration (F=ma)
The air resistance stays the same so the velocity increases. There will be no resultant force, hence no acceleration (F=ma)
The air resistance continues to increase as long as the velocity increases. When the air resistance reaches the same value as the weight there will be an increase in acceleration
