How do you calculate the net force acting on an object?

Back

The net force can be calculated by summing all the forces acting on an object, taking into account their directions. If forces are in opposite directions, subtract the smaller force from the larger one.

Define kinetic friction. How is it different from static friction?

Back

Kinetic friction is the force that opposes the motion of two surfaces sliding past each other. It is generally less than static friction, which is the force that must be overcome to start moving an object at rest.

What is a free body diagram?

Back

A free body diagram is a graphical representation used to visualize the forces acting on an object. It shows all the external forces and their directions.

Explain the significance of the normal force in dynamics.

Back

The normal force is the force exerted by a surface to support the weight of an object resting on it. It acts perpendicular to the surface and is crucial in determining the frictional force.

Front

What is the role of gravity in dynamics?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the weight of an object. It affects the motion of objects, especially in free fall.
