How can we decide whether an object is moving faster than another?
How can we decide whether an object is moving faster than another?
We can compare the distance moved by each object in unit time to determine which is moving faster.
What makes an object slow down or go faster, or change its direction of motion?
What makes an object slow down or go faster, or change its direction of motion?
An applied force can make an object slow down, go faster, or change its direction of motion.

Study Notes
Comparing Speeds
- To determine if an object is moving faster than another, compare the distance each object travels in the same amount of time. The object covering more distance in the same time is moving faster.
Forces and Motion
- Forces can cause an object to speed up, slow down, or change direction.
- A force is a push or a pull that can change an object's motion.
- Examples of forces include gravity, friction, and the force applied by a person.
Force in Action
- Kicking, hitting, pushing, and picking are all examples of applying a force to an object.
- These actions can cause an object to start moving, stop moving, or change direction.
Force and Motion Explained
- Forces directly influence the motion of an object.
- A force can cause an object to accelerate, meaning it changes its speed or direction.
- The greater the force applied, the greater the acceleration.
Everyday Examples of Force
- Opening a door, pushing a cart, throwing a ball, and lifting a weight are everyday examples involving the application of force.
Applying Force in Sports
- A goalkeeper stops a ball by applying a force against it, bringing it to rest.
- A fielder stops a ball hit by a batsman by applying a force to slow it down and catch it.
- A hockey player changes the direction of a moving puck by applying a force with their stick.
