Con Physics-Semester 1 Final Review

Front

What happens to the net force when two equal forces act on the same object in opposite directions?

Back

The net force is zero.

Front

What are the units for Force?

Back

N (Newtons)

Front

What is the force of gravity on a person or object at the surface of a planet called?

Back

Weight.

Front

If Desiree runs with a velocity of 7 m/s, how long will it take her to run 400 m?

Back

50 seconds.

Front

What is the variable for Velocity?

Back

V.

Front

Define Force in physics.

Back

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

Front

What is the formula for calculating Weight?

Back

Weight = mass × gravity (W = mg).

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is Inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating Velocity?

Back

Velocity = distance / time (V = d/t).
