What is the term for the rate of change in the velocity of an object?

Impulse
Acceleration (correct)
Force
Momentum

Which of the following is a measure of the magnitude of the change of an object's position over time?

Velocity
Displacement
Acceleration
Speed (correct)

What is the product of the mass and velocity of an object called?

Force
Acceleration
Momentum (correct)

What is the term for the combination of speed and direction of motion of an object?

Velocity (C) Signup and view all the answers

Describe the difference between speed and velocity. How does this distinction relate to an object's motion?

Velocity has both magnitude (speed) and direction. Objects can have zero velocity but still have speed due to change in direction. Signup and view all the answers

How does an object's acceleration relate to its change in velocity?

Acceleration is the rate of change of velocity; it is the change in velocity per unit time. Signup and view all the answers

What is the physical significance of momentum in relation to force and acceleration?

Momentum is the product of an object's mass and velocity. A force applied to an object changes its momentum, resulting in acceleration. Signup and view all the answers

Describe the difference between displacement and distance. How are they related to an object's velocity and acceleration?

Displacement is the net change in an object's position, while distance is the total path traveled. Velocity relates to displacement, and acceleration relates to the change in velocity. Signup and view all the answers

How does an object's impulse relate to its momentum and force?

Impulse is the change in an object's momentum, resulting from a force applied over a period of time. Signup and view all the answers
