Physics Final Review

Front

What is constant speed?

Back

Constant speed means an object is moving at the same distance over time without speeding up or slowing down.

Front

What two factors affect momentum?

Back

Momentum depends on mass and velocity.

Front

How do you calculate net force?

Back

Net force is the vector sum of all forces acting on an object. It determines the object's acceleration.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the relationship between mass and velocity in kinetic energy?

Back

Kinetic energy increases with both mass and the square of velocity.

Front

What does it mean for forces to be balanced?

Back

Balanced forces occur when the net force acting on an object is zero, resulting in no change in motion.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

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 gravitational force?

Back

Gravitational force is the attraction between two masses, proportional to their masses and inversely proportional to the square of the distance between them.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, calculated as the change in velocity divided by the time taken.
