Tina rolls a ball across the floor. what type of force is acting upon this ball? a. gravity b. friction c. push (applied) d. all of these

The forces acting on the ball are gravity, friction and applied force.

Explanation:

Tina rolls a ball across the floor. The forces acting on this ball are :

(1) Gravitational force : The force due to gravity act on this ball which is equivalent to, W = m × g

Where, m is the mass of ball and g is the acceleration due to gravity

(2) Frictional force : The force of friction always act in opposite direction of the applied force. It always opposes the direction of motion.

(3) Push (applied) : The force with which this ball is thrown is called applied force.

Hence, the correct option is (d) " all of these ".
