Mechanics and Motion

What is motion?

• The movement of objects in a straight line

• The movement of objects in a circular path

• The movement of objects at a constant velocity

• The movement of objects in any direction

What is the difference between speed and velocity?

• Speed is the rate at which an object moves, while velocity is the rate at which an object changes its position

• Speed is the rate at which an object changes its position, while velocity is the rate at which an object moves

• Speed and velocity are the same thing

• Speed and velocity have no relation to motion

What is acceleration?

• The rate at which an object changes its position

• The rate at which an object changes its velocity

• The rate at which an object changes its speed

• The rate at which an object changes its mass

What is mass?

• The amount of force acting on an object

• The amount of energy an object possesses

• The amount of matter in an object

• The amount of motion an object has

What are simple movements in mechanics?

• Objects moving in a straight line

• Objects moving in a circular path

• Objects moving at a constant velocity

• Objects moving at different speeds

What are complex movements in mechanics?

• Objects moving in a straight line

• Objects moving in a circular path

• Objects moving at a constant velocity

• Objects changing direction

What are the key concepts in mechanics?

• Forces, acceleration, energy, work, and mass

• Speed, velocity, acceleration, and mass

• Motion, velocity, acceleration, and energy

• Forces, motion, velocity, and energy
