The acceleration

The average speed

The resultant force

The displacement

The horizontal velocity stays constant and the vertical motion accelerates at g

The horizontal velocity steadily decreases over time because of the pull of gravity

The vertical acceleration is zero throughout the whole flight

Both the horizontal and vertical components accelerate at g

Every action has an equal and opposite reaction force on the other body

The resultant force equals the rate of change of momentum

An object stays at rest unless acted on by a force

Momentum is always conserved in any closed system

Kinetic energy

Speed

Momentum

Both kinetic energy and momentum

$1.0\ \text{N}$

$5.0\ \text{N}$

$40\ \text{N}$

$P = Fv$

$P = Fx$

$P = \frac{F}{v}$

$P = \frac{1}{2}Fv^2$

$mg$

$mg\sin\theta$

$mg\cos\theta$

$mg\tan\theta$

The centripetal force on the object is always zero

The object does not actually move along its path

The force is always perpendicular to the velocity

The kinetic energy of the object steadily increases

The drag force acting on the object has fallen to zero

The object is still accelerating, but only very slowly now

The weight of the falling object has become zero

The resultant force is zero and the velocity is constant

The total clockwise moment equals the total anticlockwise moment about any point

All of the forces acting on the object must be equal in size

The resultant force on the object always points directly towards the pivot point

The moment of every individual force about the pivot is zero
