Force and Motion

Front

What is Net Force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

Define Motion.

Back

A change in position of an object relative to a reference point.

Front

What is Friction?

Back

The resistance that one surface or object encounters when moving over another.

Front

What is Average Speed?

Back

The total distance traveled divided by the total time taken.

Front

What is a Newton?

Back

The SI unit of force, defined as the force required to accelerate a one-kilogram mass by one meter per second squared.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is acceleration?

Back

The rate of change of velocity of an object with respect to time.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What is gravitational force?

Back

The attractive force between two masses, proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
