Contact Forces Review - TG

Front

What is a contact force?

Back

A contact force is a force that acts at the point of contact between two objects, such as friction, tension, and normal force.

Front

What is the breaking point of an object?

Back

The breaking point is the specific amount of force that an object can withstand before it deforms or breaks.

Front

What is the normal force?

Back

The normal force is the force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

What causes unbalanced forces?

Back

Unbalanced forces occur when the total forces acting on an object are not equal, resulting in a change in motion.

Front

What is friction?

Back

Friction is a contact force that resists the motion of two surfaces sliding against each other.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, which increases with mass and speed.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, such as height above the ground.

Front

How does mass affect kinetic energy?

Back

The more mass an object has, the more kinetic energy it has when moving, as kinetic energy is proportional to mass.

Front

What is the relationship between force and motion?

Back

Force is required to change the motion of an object; an unbalanced force will cause an object to accelerate.

Front

What is an example of a contact force?

Back

Examples of contact forces include friction, tension, normal force, and air resistance.
