Study Notes
Forces and Their Effects
- A force is a push or pull that can cause an object to change its motion or shape.
Effects of Forces on Objects
- Forces can cause an object to change its motion, speed, or direction.
- Forces can also change an object's size and shape.
Types of Forces
- Muscular force is used when you push or pull an object using your muscles.
- Gravitational force is the force of attraction between Earth and any other object.
- Frictional force causes a surface to exert a force as an object moves across it or makes an effort to move across it.
- Elastic force resists the change in shape in an elastic material when it is stretched or compressed.
- Mechanical force causes an object to change its motion or start moving and can also bend or break things.
Scenarios Demonstrating Forces
- An example of a force changing the direction of motion is when you push a block of wood to the left, and it changes direction to the right.
- Applying muscular force is demonstrated by pushing or pulling an object using your muscles.
- Work is said to be done when an object is moved or lifted against a force, such as gravity.
- Energy involves the capacity or ability to do work.
Frictional Force
- Frictional force causes an object to stop or slow down, such as when a toy car stops after being pushed due to the surface exerting a force opposite to the direction of movement.
