Physics - Fall Semester Review

Front

What is the formula for calculating horizontal velocity?

Back

Horizontal velocity (v) can be calculated using the formula: v = distance / time.

Front

What is centripetal force?

Back

Centripetal force is the force required to keep an object moving in a circular path, directed towards the center of the circle.

Front

How do you calculate centripetal force?

Back

Centripetal force (F_c) can be calculated using the formula: F_c = (mass * velocity^2) / radius.

Front

What is the definition of unbalanced forces?

Back

Unbalanced forces are forces that cause an object to accelerate, resulting in a change in motion.

Front

What is the acceleration of an object?

Back

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

Front

What is the formula for acceleration?

Back

Acceleration (a) can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the significance of a negative acceleration?

Back

Negative acceleration indicates that an object is slowing down or decelerating.

Front

What is the relationship between speed and distance?

Back

Speed is defined as the distance traveled per unit of time, calculated as speed = distance / time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the effect of gravity on falling objects?

Back

Gravity causes objects to accelerate downwards at approximately 9.81 m/s², regardless of their mass.
