Motion and Velocity Quiz

Study Notes

Velocity is the rate of change of position
Measured in meters per second (m/s)
Can be positive (moving in one direction) or negative (moving in the opposite direction)
Velocity is a vector quantity, having both magnitude and direction

Kinematics is the study of the motion of objects without considering the forces that cause the motion
Describes the motion of objects using parameters such as:
- Position (x)
- Velocity (v)
- Acceleration (a)
- Time (t)
Kinematic equations:
- v = Δx / Δt
- a = Δv / Δt
- v = v0 + at

First Law (Law of Inertia):
- An object at rest will remain at rest, and an object in motion will continue to move with a constant velocity, unless acted upon by an external force
- Inertia is the tendency of an object to resist changes in its motion
Second Law (F = ma):
- The force applied to an object is equal to the mass of the object multiplied by its acceleration
- F = ma
Third Law (Action and Reaction):
- For every action, there is an equal and opposite reaction
- When two objects interact, they apply forces to one another that are equal in magnitude and opposite in direction

Speed is the magnitude of velocity (i.e., the rate of change of position without considering direction)
Measured in meters per second (m/s)
Speed is a scalar quantity, having only magnitude and no direction
Calculated using the formula: speed = Δx / Δt

Velocity is the rate of change of position, measured in m/s.
It can be positive (moving in one direction) or negative (moving in the opposite direction).
Velocity is a vector quantity, having both magnitude and direction.

Kinematics studies the motion of objects without considering the forces that cause the motion.
It describes the motion of objects using parameters such as position (x), velocity (v), acceleration (a), and time (t).
Kinematic equations include v = Δx / Δt, a = Δv / Δt, and v = v0 + at.

An object at rest will remain at rest, and an object in motion will continue to move with a constant velocity, unless acted upon by an external force.
Inertia is the tendency of an object to resist changes in its motion.

The force applied to an object is equal to the mass of the object multiplied by its acceleration.
The formula is F = ma.

For every action, there is an equal and opposite reaction.
When two objects interact, they apply forces to one another that are equal in magnitude and opposite in direction.
