Physics Semester 1

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is the formula for calculating momentum?

Back

The formula for momentum (P) is P = m * v, where m is mass and v is velocity.

Front

What is the Normal force?

Back

The 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 does Newton's First Law state?

Back

Newton's First Law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is displacement?

Back

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

Front

What is the difference between distance and displacement?

Back

Distance is a scalar quantity that refers to how much ground an object has covered, while displacement is a vector quantity that refers to how far out of place an object is.

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that the total momentum of a closed system remains constant if no external forces act on it.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What happens to momentum during a collision?

Back

During a collision, the total momentum before the collision is equal to the total momentum after the collision, assuming no external forces are acting.

Front

What is a vector quantity?

Back

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