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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

Define force in physics.

Back

A force is a push or pull on an object that can cause it to accelerate, change direction, or change shape.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

Explain the concept of energy conservation.

Back

Energy conservation states that energy cannot be created or destroyed, only transformed from one form to another.

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, commonly gravitational potential energy, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms, while weight is the force exerted by gravity on that mass, measured in newtons.

Front

Define acceleration.

Back

Acceleration is the rate of change of velocity of an object, calculated as a = (final velocity - initial velocity) / time.

Front

What is the principle of inertia?

Back

The principle of inertia states that an object will remain at rest or in uniform motion unless acted upon by an external force.

What is the law of universal gravitation?

Back

The law of universal gravitation states that every point mass attracts every other point mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
