Newton Laws & Free Body Diagrams

Front

What does the length of an arrow represent in a free body diagram?

Back

The length of the arrow shows the magnitude of the force.

Front

What is the NET Force?

Back

The NET Force is the overall force acting on an object, taking into account all individual forces. For example, if there are forces of 8 N to the left and 4 N to the right, the NET Force is 4 N to the left.

Front

Define friction in the context of forces.

Back

Friction is the force that resists the sliding motion of two surfaces that are touching.

Front

If an object experiences 8 N to the left and 4 N to the right, what is the net force and is it balanced?

Back

The net force is 4 N to the left and it is not balanced.

Front

What forces act on a leopard lying on a log?

Back

The forces acting on a leopard lying on a log are the gravitational force (Fg) and the normal force (Fn).

Front

What is a free body diagram?

Back

A free body diagram is a graphical representation used to visualize the forces acting on an object.

Front

What does the normal force (Fn) represent?

Back

The normal force (Fn) is the support force exerted upon an object that is in contact with a surface.

Front

How does friction affect motion?

Back

Friction opposes the motion of an object, making it harder for the object to slide or move.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects that are not moving, while kinetic friction acts on objects that are sliding over each other.

Front

What is the formula for calculating net force?

Back

Net Force (F_net) = Sum of all forces acting on an object.
