PRACTICE QUESTIONS WITH CORRECT ANSWERS (2024
UPDATE)
Acceleration equation - ANSWER- final velocity-initial velocity/time
Uniform acceleration - ANSWER- constant acceleration
Uniform acceleration equation - ANSWER- final velocity^2-initial velocity^2 = 2 x
acceleration x distance
Distance-time graph - ANSWER- gradient = speed
Velocity-time graph - ANSWER- shows how velocity is related to time
Friction - ANSWER- A force that opposes motion between two surfaces that are in contact
Drag - ANSWER- resistance by friction from air or water moving over a surface
Terminal velocity - ANSWER- the constant velocity of a falling object when the force of air
resistance is equal in magnitude and opposite in direction to the force of gravity
Factors affecting terminal velocity - ANSWER- shape and area
A zero resultant force means - ANSWER- no acceleration
Newton's second law - ANSWER- F = ma
Inertia - ANSWER- The tendency of an object to resist a change in motion
