DCP #2 Review 24/25

Front

What are balanced forces?

Back

Forces that have a net force of zero, meaning they do not cause a change in motion.

Front

What are unbalanced forces?

Back

Forces that result in a net force greater than zero, causing an object to accelerate.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance / Time).

Front

What happens when two skaters push off each other?

Back

They move in opposite directions; the skater with less mass will accelerate more.

Front

What type of energy transformation occurs in a microwave oven?

Back

Electrical energy is transformed into thermal energy, light energy, and sound energy.

Front

What is the relationship between mass and acceleration when forces are applied?

Back

According to Newton's second law, acceleration is inversely proportional to mass when the same force is applied (F = ma).

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating net force?

Back

Net Force = Sum of all forces acting on an object.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).
