Force Diagrams

Front

What is a force diagram?

Back

A visual representation of all the forces acting on an object, showing their direction and magnitude.

Front

What does it mean for forces to be in equilibrium?

Back

Forces are in equilibrium when the net force acting on an object is zero, resulting in no change in motion.

Front

If a hockey puck is moving at a constant velocity, what can be said about the forces acting on it?

Back

The forces acting on the puck are balanced, meaning the net force is zero.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; it is directly related to mass.

Front

How do you calculate net force when two forces act in the same direction?

Back

Add the magnitudes of the two forces together.

Front

What happens to the velocity of an object if the net force acting on it is zero?

Back

The object's velocity remains constant.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What does a leftward force on a crate indicate about its motion?

Back

The crate is being pushed to the left, and if the speed is constant, other forces must balance this force.

Front

What is the effect of friction on a moving object?

Back

Friction opposes the motion of the object, acting in the opposite direction to its movement.
