What is shown by thearea under a velocity-time graph	Change in displacement	0%
What is shown by the area under an acceleration-time graph	Change in velocity	0%
What happens to the horizontal velocity in projectile motion	Constant	0%
What is the equation used for the horizontal component of projectile motion	Displacement = Velocity x time (since horizontal velocity is constant)	0%
Define friction	Force that acts between surfaces to oppose motion	0%
What is the effect of air resistance on horizontal projectile motion	Horizontal speed is reduced and hence range is reduced.	0%
The acceleration of a projectile	Is always g downwards	0%
What are the units of acceleration	ms^-2	0%
What is the effect of mass on the acceleration for an object in free-fall	None	0%
Describe the path of projectiles	Parabola / parabolic	0%
Define velocity	Rate of change of displacement (vector)	0%
Define speed	Rate of change of distance (scalar)	0%
Define acceleration	Rate of change of velocity (vector)	0%
What is the effect of air resistance on the motion of an object projected above the horizontal	Reduces the maximum height reached and makes the descent of the projectile steeper than the ascent.	0%
Why can SUVAT equations can be used for the vertical component of projectile motion	Since the motion is in a single direction with a constant acceleration	0%
What is shown by the gradient of a distance-time graph	Speed	0%
Define constant velocity	Speed and direction of motion don't change	0%
Define displacement	The distance of an object from a point in a specific direction (vector)	0%
Define air resistance	The drag force exerted due to friction between the projectile and the air. Always acts in the opposite direction to motion and increases with speed.	0%
What are the forces on an object falling at terminal velocity	The drag force must be equal and opposite to the weight	0%
Define inertia	The resistance of an object to changes in its motion	0%
If a projectile returns to its starting height initial and final velocities have	the same magnitude	0%
When would you use a SUVAT equation	Used for motion of an object along a straight line with constant acceleration	0%
What is shown by the gradient of a displacement-time graph	Velocity	0%
What is the vertical component of the velocity when at the maximum height?	Zero	0%
An object projected horizontally has an initial vertical velocity of	Zero	0%
