Forces and Motion PreAssessment

Front

What is Newton's second law of motion?

Back

Newton's second law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = m * a).

Front

What is the relationship between force, mass, and acceleration according to Newton's second law?

Back

Force is directly proportional to mass and acceleration.

Front

What is the formula to calculate net force?

Back

Net force = Sum of all forces.

Front

How does friction affect the motion of an object?

Back

Friction opposes the motion of an object.

Front

What property of matter causes an object in motion to stay in motion unless acted upon by an external force?

Back

Inertia.

Front

According to Newton's first law of motion, what will happen to an object at rest?

Back

An object at rest will remain at rest unless acted upon by an external force.

Front

What is the definition of force?

Back

A force is a push or pull acting upon an object.

Front

What is mass?

Back

Mass is the amount of matter in an object, typically measured in kilograms.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

What is the effect of gravity on objects in motion?

Back

Gravity pulls objects toward the center of the Earth, affecting their motion.
