What is mechanical motion?
Click to flip
Mechanical motion refers to the change in position of an object over time.
Click to flip
What are the types of mechanical motion?
Click to flip
The main types of mechanical motion are translational, rotational, and oscillatory motion.
Click to flip
What is translational motion?
Click to flip
Translational motion occurs when an object moves along a path in any of the three dimensions.
Click to flip
What is rotational motion?
Click to flip
Rotational motion occurs when an object spins around an internal axis.
Click to flip
What is oscillatory motion?
Click to flip
Oscillatory motion is repetitive motion back and forth around an equilibrium position.
Click to flip
How is speed defined in mechanical motion?
Click to flip
Speed is defined as the distance traveled per unit of time.
Click to flip
What unit is speed typically measured in?
Click to flip
Speed is typically measured in meters per second (m/s) or kilometers per hour (km/h).
Click to flip
What is velocity?
Click to flip
Velocity is speed in a given direction.
Click to flip
How does velocity differ from speed?
Click to flip
Velocity includes direction, while speed does not.
Click to flip
What is acceleration?
Click to flip
Acceleration is the rate of change of velocity over time.
Click to flip
What is the formula for calculating speed?
Click to flip
Speed is calculated as distance divided by time (speed = distance/time).
Click to flip
Can mechanical motion occur without a force?
Click to flip
Yes, motion can continue without a force due to inertia, but a force is needed to change that motion.
Click to flip
What does the term 'inertia' mean?
Click to flip
Inertia is the tendency of an object to resist a change in motion.
Click to flip
What is meant by 'uniform motion'?
Click to flip
Uniform motion means moving at a constant speed in a straight line.
Click to flip
What is an example of mechanical motion in everyday life?
Click to flip
An example is a car driving down the road.
