Physics First Semester Final

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction, such as displacement.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken. Formula: Speed = Distance / Time.

Front

Which object has more inertia: a bowling ball or a tennis ball?

Back

A bowling ball has more inertia because it has greater mass.

Front

When does a pole vaulter have the greatest gravitational potential energy?

Back

A pole vaulter has the greatest gravitational potential energy just before he starts to fall to the ground.

Front

What force opposes the motion of a sky diver?

Back

Air resistance opposes the motion of a sky diver.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, including direction.

Front

Define inertia.

Back

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

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, calculated as PE = mgh.

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 formula for calculating acceleration?

Back

Acceleration is calculated using the formula: Acceleration = (Final Velocity - Initial Velocity) / Time.
