Understanding Forces. push or pull that tends to cause an object to change its movement or shape. The actual effect of a force relies on these three things: Break into groups of two, think of an action in sports (ex. kicking a soccer ball, sumo wrestling, etc.), act out the action, and explain the forces that are being exerted.

When an object lies on a surface, the surface exerts an equal and opposite force. The component of this force that is perpendicular to the surface is called the normal force. Example: The force exerted by the table on a book lying on it.
The forces applied to an object in order to displace or deform it is called the applied force. Example: The force with which a person pushes a cart.
The tensionor tension force is a force experienced by a rope, string, or cable pulled from the opposite end. Example: The force experienced by a rope when a person pulls a bucket of water from a well.
The frictionforce is the force of resistance to an object’s motion. There are two main types of friction force. A. Static Friction Static friction arises when the applied force is such that an object remains stationary relative to the surface. Example: The resistance offered by a stationary box when a person tries to push it. B. Kinetic Friction Ki...
The force of resistance offered by air to an object moving through it is called air resistance. Example: The resistance offered by air when a ball falls through it.
The force exerted by a spring when compressed or extended is called spring force. Example: The force used to measure weight with a weighing scale.
When an object is immersed in a fluid, wholly or partially, the fluid exerts an upward force opposite its weight. This phenomenon is known as buoyancy, and the upward thrust is known as the buoyant force. Example: Boat sailing on the river.
When an object moves through a fluid, like air or water, it experiences a drag force, also known as drag resistance. Example: A car driving on a highway.
Feb 3, 2023 · A contact force is defined as the force between two objects that are in physical contact. For example, kicking a soccer ball is a contact force since physical contact is between the foot and the ball. A non-contact force is defined as the force between two objects that are not in physical contact.
- Forces and Motion – What is a force? A force is a push or a pull. Forces can make object moves or stop, speed them up or slow them down. If you push a toy car it moves, if you push it harder it moves faster.
- Friction Experiments for Kids. What is Friction? Friction tries to stop objects sliding past each other. Friction allows things to start and stop moving and slows them down.
- Friction Experiments. Find out why you slip and slide more on smooth surfaces than rougher surfaces with this slipping and sliding activity. Do be careful not to fall over though.
- Gravity Experiments for kids. A film canister rocket is a great demonstration of lots of different forces, but it falls back to the ground thanks to gravity.
