Physics Semester Final Review

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

At the top of its path, if an object is thrown straight up into the air, its speed is?

Back

zero

Front

How do you solve for mass, using Newton's 2nd law?

Back

m = F/a

Front

What are the units and variables for force?

Back

Newtons (N), F (force), m (mass), a (acceleration)

Front

What is Newton's 2nd Law?

Back

F = ma

Front

What is the formula for calculating acceleration?

Back

a = (final velocity - initial velocity) / time

Front

What is the definition of force?

Back

Force is an interaction that causes an object to change its velocity, measured in Newtons (N).

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass × gravity (W = mg).

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as KE = 1/2 mv².

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, calculated as PE = mgh.
