What is inertia?

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

• Inertia is the force that causes an object to accelerate.

• Inertia is the measure of an object's mass.

• Inertia is the energy stored in an object due to its motion.

What is mass?

• The weight of an object measured in grams.

• The amount of matter in an object, usually measured in kilograms.

• The volume of an object measured in liters.

• The density of an object measured in kilograms per cubic meter.

What is the formula for calculating force?

• Force = mass + acceleration (F = m + a)

• Force = mass × acceleration (F = m × a)

• Force = mass / acceleration (F = m / a)

• Force = mass - acceleration (F = m - a)

What is the effect of a balanced force on the motion of an object?

• A balanced force increases the speed of the object.

• A balanced force changes the direction of the object.

• A balanced force does not change the motion of an object.

• A balanced force causes the object to accelerate.

If two objects collide with the same force but have different masses, how will their changes in velocity compare?

• Their changes in velocity will be the same.

• Their changes in velocity will be different.

• Their changes in velocity will be negligible.

• Their changes in velocity will be equal to their masses.

What happens to an object's motion when no net force acts on it?

• The object will remain at rest or continue moving at a constant velocity.

• The object will accelerate in the direction of the applied force.

• The object will come to a complete stop immediately.

• The object will change direction randomly.

Define force in the context of motion.

• A type of energy that causes objects to move.

• A push or pull that can change the motion of an object.

• The speed at which an object moves in a given direction.

• The mass of an object multiplied by its acceleration.

What is the relationship between mass and acceleration when a constant force is applied?

• As mass increases, acceleration increases if the force is constant.

• As mass increases, acceleration decreases if the force is constant.

• Mass and acceleration are independent of each other when a constant force is applied.

• Mass has no effect on acceleration when a constant force is applied.

What is the role of gravity in motion?

• Gravity pulls objects toward the Earth, affecting their motion.

• Gravity pushes objects away from the Earth, increasing their speed.

• Gravity has no effect on the motion of objects in space.

• Gravity only affects objects that are in free fall.

What force holds us to the Earth's surface?

• Magnetism

• Friction

• Gravity

• Electromagnetism
