Physics Semester One Exam SY2024-25

Front

What is the unit of speed?

Back

m/s

Front

How is the gravitational force between two objects related to their mass?

Back

They are directly proportional.

Front

A coin is released from rest from the top of a tower and hits the ground after 1.5 seconds. What is the speed of the coin as it hits the ground?

Back

15 m/s

Front

Which law of motion states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass?

Back

Newton's second law of motion.

Front

Which of these is not a vector quantity?

Back

Time.

Front

Define speed in physics.

Back

Speed is the distance traveled per unit of time.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is Newton's first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have magnitude only, while vector quantities have both magnitude and direction.

Front

What is the formula for gravitational force between two masses?

Back

F = G * (m1 * m2) / r^2, where G is the gravitational constant.
