What is the formula to calculate acceleration?

acceleration = final velocity / time

acceleration = (final velocity - initial velocity) / time

acceleration = (final velocity * initial velocity) / time

acceleration = (final velocity + initial velocity) / time

State the equation of motion for uniformly accelerated motion.

s = ut + at^2

s = ut + (1/2)at

s = vt + (1/2)at^2

s = ut + (1/2)at^2

Explain the concept of free fall in the context of uniformly accelerated motion.

Free fall in the context of uniformly accelerated motion refers to the motion of an object falling solely under the influence of gravity, experiencing a constant acceleration of approximately 9.81 m/s^2.

Free fall occurs only in a vacuum environment.

Free fall is when an object moves upwards due to gravity.

Free fall involves a variable acceleration depending on the object's mass.

How does air resistance affect the motion of an object in free fall?

Air resistance has no effect on the motion of an object in free fall

Air resistance increases the speed of the object in free fall

Air resistance causes the object in free fall to move in a straight line

Air resistance slows down the object in free fall, eventually reaching a terminal velocity where the forces balance out.
