A force is simply a push or a pull in a particular direction. Forces result from an object’s interaction with another object.

## What is force in science grade 4?

A force is a push or pull. Forces include magnetism, gravity, and friction. Gravity causes a pull between two objects. For example, everything on Earth pulls toward its surface.

What are the 5 forces in science?

Action-at-a-Distance Forces

• Applied Force.
• Gravitational Force.
• Normal Force.
• Frictional Force.
• Air Resistance Force.
• Tension Force.
• Spring Force.

What are the four main types of forces?

fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay.

### What are the 5 effects of force?

A force can produce the following effects:

• A force can move a stationary object.
• A force can stop a moving object.
• A force can change the speed of a moving object.
• A force can change the direction of a moving object.
• A force can change the shape and size of an object.

### What are contact forces 5 examples?

Examples of contact forces include:

• Reaction force. An object at rest on a surface experiences reaction force .
• Tension. An object that is being stretched experiences a tension force.
• Friction. Two objects sliding past each other experience friction forces.
• Air resistance.

What are 3 examples of balanced forces?

Here are some examples of situations involving balanced forces.

• Hanging objects. The forces on this hanging crate are equal in size but act in opposite directions.
• Floating in water. Objects float in water when their weight is balanced by the upthrust from the water.
• Standing on the ground.

What are 3 examples of unbalanced forces?

Examples of unbalanced forces

• Kicking a soccer ball.
• The up and down movement in a seesaw.
• The taking-off of a Rocket.
• Skiing along the mountain slopes.
• Hitting a baseball.
• A turning vehicle.
• Drowning of an object.
• Apple falling on the ground.
