Force Diagrams

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It acts parallel to the surfaces in contact and can cause an object to slow down or stop.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in no change in motion of an object.

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in the motion of an object, such as speeding up, slowing down, or changing direction.

What happens to a car moving at a constant speed in a straight line?

Back

The forces acting on the car are balanced, meaning the forward force (like the engine) is equal to the opposing forces (like friction and air resistance).

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 gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

What is an example of an unbalanced force?

Back

An example of an unbalanced force is a marble rolling down a ramp, where the force of gravity is greater than the opposing forces, causing it to speed up.

What is the role of applied force?

Back

Applied force is a force that is applied to an object by a person or another object, which can cause the object to move or change its motion.

How does friction affect motion?

Back

Friction opposes motion, meaning it can slow down or stop moving objects, and it is essential for activities like walking or driving.
