Semester 1 Exam Physics 2024

Front

What is the definition of constant speed?

Back

Constant speed means that an object covers equal distances in equal intervals of time, regardless of how small those intervals are.

Front

What does Newton's 3rd law state?

Back

Newton's 3rd law states that for every action, there is an equal and opposite reaction.

Front

What is normal force?

Back

Normal force is the force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

What is a free-body diagram?

Back

A free-body diagram is a graphical representation used to visualize the forces acting on an object.

Front

What are the units for acceleration?

Back

The units for acceleration are meters per second squared (m/s²).

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, force is equal to mass times acceleration (F = ma).

Front

What is the definition of frictional force?

Back

Frictional force is the force that opposes the relative motion of two surfaces in contact.

Front

What is tension force?

Back

Tension force is the force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

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 inertia?

Back

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