FORCES

What is force?

• A measure of an object's mass

• The speed of an object in motion

• A push or pull acting upon an object

• The energy stored in an object's position

What is inertia?

• The resistance of an object to change in its state of motion

• The force exerted by an object in motion

• The acceleration of an object due to gravity

• The energy stored in an object's position

When two forces act in opposite directions, how can you find the net force?

• Add the magnitudes of the two forces

• Subtract the magnitudes of the two forces

• Divide the magnitudes of the two forces

• Multiply the magnitudes of the two forces

What is momentum?

• The resistance of an object to change in its state of motion

• The speed of an object in motion

• The product of an object's mass and velocity

• The energy stored in an object's position

What is friction?

• A measure of an object's mass

• The force that opposes motion between surfaces in contact

• A push or pull acting upon an object

• The energy stored in an object's position

What happens to an object's motion when unbalanced forces act upon it?

• The object accelerates in the direction of the stronger force

• The object decelerates in the direction of the weaker force

• The object remains at a constant speed

• The object changes direction randomly

How do balanced forces affect the motion of an object?

• They cause the object to accelerate

• They cause the object to decelerate

• They cause the object to remain at rest

• They cause the object to change direction

What is the relationship between force and acceleration?

• Force and acceleration are unrelated

• Force is directly proportional to acceleration

• Force is inversely proportional to acceleration

• Force causes deceleration, not acceleration

How does mass affect an object's inertia?

• Mass has no effect on inertia

• Greater mass results in greater inertia

• Less mass results in greater inertia

• Mass only affects acceleration, not inertia

How does the law of universal gravitation explain the attraction between objects?

• It states that objects are attracted to each other by a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them

• It states that objects are repelled from each other by a force that is inversely proportional to the product of their masses and directly proportional to the square of the distance between them

• It states that objects are attracted to each other by a force that is inversely proportional to the product of their masses and directly proportional to the distance between them

• It states that objects are repelled from each other by a force that is directly proportional to the product of their masses and inversely proportional to the distance between them
