What is the total distance you travel, from stimulus to stopped called?
Stopping distance
What is the time you take to respond to a stimulus called?
reaction time
What is the name for the maximum velocity a falling object can reach?
terminal velocity
What does the gradient of this distance time graph give you?
Speed
What factors affect the size of the air resistance an object feels?
Speed of the object, shape of the object, density of the fluid.
What does a horizontal line on a velocity-time graph mean?
The object is moving with a constant velocity.
Which of Newton's laws is this: Acceleration is proportional to the resultant force and inversely proportional to the mass.
Newton's second law
What does a curved distance time graph mean the object was doing?
accelerating
What is the distance you travel whilst you are applying the brakes called?
Braking distance
Which of the two cars (red or Blue) was travelling the fastest?
Blue
Why does the distance always increase, even if you turn around and come back?
Distance is scalar - so only has size
Which of Newton's laws is this: If object A exerts a force on object B, then object B will exert an equal and opposite force on object A.
Newton's 3rd law
The tendency of objects to continue in their state of rest or of uniform motion is called...
inertia
Which of Newton's laws is this: If the resultant force acting on an object is zero and the object is stationary, it will remain stationary.
Newton's 1st Law
Grandad Timmy is slowly changing speed from 0.2 to 0.4m/s. Is he accelerating?
Yes - any change in velocity is acceleration.
If this runner was to speed up, what would happen to the gradient of this distance time graph?
The gradient would increase
What does a horizontal line on a distance-time graph mean?
The object is stationary
Timmy has just jumped out of a plane. As they accelerate, what happens to the air resistance?
Air resistance increases with speed
What does the gradient of this velocity time graph give you?
acceleration
A car travels at a constant speed around a corner, is it accelerating?
Yes - acc'n is a changing velocity, and velocity includes direction.
Timmy is sky diving, his weight and air resistance are balanced. Describe his motion...
Moving with a constant velocity (terminal velocity)
What does the area under a velocity-time graph give you?
The displacement
When these two collide, Newton's third law says they feel the same force. So why do they move back with different velocities?
Newton's second law says that acceleration is inversely proportional to mass
What is the distance you travel, whilst you are reacting to a stimulus called?
Thinking distance
