Force Diagrams

Front

What is a force diagram?

Back

A force diagram is a visual representation that shows all the forces acting on an object, including their direction and magnitude.

Front

What is the normal force?

Back

The normal force is the support force exerted upon an object that is in contact with a surface, acting perpendicular to the surface.

Front

What is frictional force?

Back

Frictional force is the force that opposes the motion of an object when it is in contact with another surface.

Front

What is net force?

Back

Net force is the total force acting on an object after all the individual forces are combined, determining the object's acceleration.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting in one direction and subtracting the forces acting in the opposite direction.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = m × a, where F is force, m is mass, and a is acceleration.

Front

What is the weight of an object?

Back

Weight is the force exerted by gravity on an object, calculated as W = m × g, where g is the acceleration due to gravity (approximately 9.8 m/s² on Earth).

Front

How do you find the mass of an object from its weight?

Back

Mass can be found from weight using the formula m = W/g, where W is weight and g is the acceleration due to gravity.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, calculated as a = (final velocity - initial velocity) / time.

Front

If a 2kg bird is pushed by the wind with a force of 2N, what is its acceleration?

Back

The acceleration of the bird is 1 m/s².
