Questions and Answers
Which statement correctly describes inertia?
Which statement correctly describes inertia?
- Inertia can change when an external force is applied.
- Inertia refers to the speed of an object in motion.
- Inertia is a measure of mass and remains constant unless mass changes. (correct)
- Inertia is only significant for objects in motion.
What is the correct relationship between mass, velocity, and momentum?
What is the correct relationship between mass, velocity, and momentum?
- Momentum equals mass multiplied by velocity. (correct)
- Momentum is a measure of the force applied to the mass.
- Momentum is inversely proportional to velocity.
- Momentum is independent of mass.
How does the force required to change momentum relate to time?
How does the force required to change momentum relate to time?
- Shorter time decreases the required force for any change in momentum.
- Time does not affect the force needed to change momentum at all.
- Longer time decreases the required force for any change in momentum. (correct)
- The force required is constant regardless of the time taken.

Study Notes
Newton's First Law of Motion
- A body at rest stays at rest, and a body in uniform motion stays in uniform motion unless an unbalanced force acts on it.
- Inertia is the property of a body to resist changes in its state of motion.
- Mass measures the amount of matter in a body. Inertia is directly proportional to mass.
Newton's Second Law of Motion
- Force is equal to the rate of change of momentum.
- Force is directly proportional to the rate of change in momentum.
- The formula for force is F = Δp/Δt, where F is force, Δp is the change in momentum, and Δt is the change in time.
- Momentum is the product of mass and velocity. Momentum is a vector quantity.
- The formula for momentum is p = mv, where p is momentum, m is mass, and v is velocity.
- Force and momentum are related by the equation F = ma, where F is force, m is mass and a is acceleration.
Momentum
- Momentum is a measure of the quantity of motion of a body.
- It is a vector quantity, meaning it has both magnitude and direction.
- Momentum is equal to the mass of the body multiplied by its velocity.
- The direction of momentum is the same as the direction of the velocity.
- Momentum is directly proportional to the mass and velocity of an object.
