What is the definition of force?
Force is an interaction that causes an object to change its motion.
Force is a type of mass that resists motion.
Force is the amount of energy in an object.
Force is the speed at which an object moves.
What is Newton's first law of motion?
An object will remain at rest or in uniform motion unless acted upon by an external force.
An object will accelerate indefinitely without any force.
An object will change direction only when a force is applied.
An object will only move if a force is applied continuously.
How does mass affect the acceleration of an object?
Acceleration is independent of mass.
Mass affects acceleration inversely; greater mass results in lower acceleration for a given force.
Greater mass always increases acceleration.
Mass has no effect on acceleration.
What is the formula for calculating force?
F = m * a
F = m + a
F = m / a
F = m - a
What is the difference between speed and velocity?
Speed is a vector; velocity is scalar.
Speed is scalar; velocity is vector (includes direction).
Speed measures distance; velocity measures time.
Speed is always constant; velocity can change.
What is inertia?
Inertia is the force that causes an object to move.
Inertia is the resistance of an object to changes in its motion.
Inertia is the speed of an object in motion.
Inertia is the energy stored in an object at rest.
How do balanced and unbalanced forces affect motion?
Balanced forces cause acceleration in all cases.
Balanced forces maintain motion, while unbalanced forces change motion.
Balanced forces always stop motion.
Unbalanced forces have no effect on motion.
What is the role of friction in motion?
Friction enables and controls motion by providing the necessary grip between surfaces.
Friction reduces motion by creating a barrier between surfaces.
Friction only occurs in liquids and has no role in solid surfaces.
Friction has no effect on motion and is irrelevant in physics.
What is gravitational force?
Gravitational force is the energy produced by a mass.
Gravitational force is the attraction between two masses.
Gravitational force is the force that keeps objects in motion.
Gravitational force is the repulsion between two masses.
How does air resistance affect falling objects?
Air resistance increases the speed of falling objects.
Air resistance has no effect on falling objects.
Air resistance slows down falling objects and leads to a terminal velocity.
Air resistance only affects objects that are not falling vertically.
What is the relationship between force, mass, and acceleration?
Force is the same as mass plus acceleration (F = m + a).
Acceleration is independent of mass and force (a = m / F).
Mass is equal to force divided by acceleration (m = F / a).
Force is equal to mass multiplied by acceleration (F = m * a).
What is the concept of momentum?
Momentum is the product of mass and velocity.
Momentum is the force applied to an object.
Momentum is the distance traveled by an object.
Momentum is the energy stored in an object.
How do you calculate the momentum of an object?
momentum (p) = mass (m) - velocity (v)
momentum (p) = mass (m) × velocity (v)
momentum (p) = mass (m) + velocity (v)
momentum (p) = mass (m) ÷ velocity (v)
What is the effect of a net force on an object?
A net force decreases the object's speed.
A net force has no effect on the object's motion.
A net force causes an object to accelerate.
A net force causes an object to remain at rest.
What is the difference between contact and non-contact forces?
Contact forces are always stronger than non-contact forces.
Contact forces involve direct interaction; non-contact forces operate at a distance.
Non-contact forces require physical touch to act.
Contact forces can only occur in liquids and gases.
