Inertia: Mass is a measure of an object's inertia—its tendency to resist changes in its state of motion. An object with more mass has more inertia and requires a greater force to accelerate at the same rate as an object with less mass.
What does mass measure in terms of an object's motion?
An object's inertia
An object's velocity
An object's acceleration
An object's weight
Which of the following statements is true about inertia?
An object with more mass has less inertia.
An object with less mass requires more force to accelerate.
An object with more mass requires greater force to accelerate.
Inertia is unrelated to mass.
How does mass affect the force required to accelerate an object?
More mass requires less force.
Less mass requires more force.
More mass requires greater force.
Mass does not affect the force required.
What happens to an object's inertia if its mass increases?
Inertia decreases.
Inertia remains the same.
Inertia increases.
Inertia becomes zero.
Which concept explains why a heavier object is harder to move than a lighter one?
Velocity
Inertia
Acceleration
Weight
If two objects have different masses, how will their acceleration differ under the same force?
The object with more mass will accelerate faster.
The object with less mass will accelerate faster.
Both objects will accelerate at the same rate.
Acceleration is independent of mass.
What is the relationship between mass and inertia?
Mass and inertia are inversely proportional.
Mass and inertia are directly proportional.
Mass and inertia are unrelated.
Mass is the square of inertia.
What is the acceleration of softball if it has a mass of 0.5 kg and hits the catcher's glove with a force of 25 N?
Your own car has a mass of 2000 kg. If your car produces a force of 5000 N, how fast will it accelerate?
Your own car has a mass of 3000 kg. If your car produces a force of 6000 N, how fast will it accelerate?
(a) is the rate at which velocity changes. If the change in velocity is positive, so is acceleration. If the change in (b) is negative, so is acceleration.
(c) is the sum of all forces acting upon the object.
(d) states that an object’s acceleration is directly proportional to the magnitude of the net force acting upon the object and inversely proportional to the object’s mass.
Force is the sum of all forces acting upon the object's (a) and its (b)
Acceleration is (c) proportional to force and (d) proportional to mass.
The equation F = ma can be rewritten to solve for acceleration by (e) both sides of the equation by the variable m.
