Name the missing force....

• gravity force

• normal force

• frictional force

• applied force

Answer explanation

The normal force is the support force exerted by a surface perpendicular to an object resting on it. It balances the weight of the object, making it the missing force in scenarios involving contact with surfaces.

Name the missing force...

• applied force

• gravity force

• normal force

• frictional force

Answer explanation

The applied force is the external force acting on an object, necessary to initiate or change its motion. In this context, it is the missing force that causes the object to move, distinguishing it from gravity, normal, and frictional forces.

Name the missing force...

• frictional force

• gravity force

• applied force

• normal force

Answer explanation

The missing force is the frictional force, which opposes the motion of objects. It is essential in scenarios where surfaces interact, making it the correct choice among the options provided.

The down-arrow in this diagram is most-likely:

• gravity

• normal

• a push or pull

• friction

Answer explanation

The down-arrow in the diagram represents gravity, as it indicates the force pulling objects toward the Earth. Other options like normal, push or pull, and friction do not typically represent a downward force in this context.

If this box is in free fall, What is the top Force

• Normal Force

• Frictional Force

• Gravity Force

• Applied Force

Answer explanation

In free fall, the only force acting on the box is gravity. However, if we consider the forces at the top of the box, the frictional force is the only one that can act against motion, making it the top force in this scenario.

If this box is in free fall, What is the downward Force

• Normal Force

• Frictional Force

• Gravity Force

• Applied Force

Answer explanation

In free fall, the only force acting on the box is the force of gravity, which pulls it downward. Therefore, the correct answer is Gravity Force.

Which way is the net force?

• Downward

• Upward

• Right

• Left

Answer explanation

The net force is directed downward, indicating that the forces acting on the object result in a net force in that direction, likely due to gravity or other downward influences.

Which way is motion?

• Not enough info

• Right-Gravity is strong

• Right-Opposite of Frictional Forces

• Right-The force is greater

Answer explanation

The correct choice is 'Right-Opposite of Frictional Forces' because motion typically occurs in the direction that opposes friction, allowing an object to move freely. Other options do not accurately describe the direction of motion.

Describe the motion of this

• Speeding up to the right

• Slowing down to the left

• Constant speed so no acceleration

• Not enough info

Answer explanation

The correct choice is 'Speeding up to the right' because it indicates an increase in velocity in the positive direction. This suggests that the object is accelerating in that direction.

Describe the force

• No net force

• Net force downward

• Net force to the right

• Not enough info

Answer explanation

The correct choice is 'Net force to the right' because it indicates a directional force acting in that direction, suggesting an imbalance of forces that results in movement or acceleration to the right.
