Force and Motion I

Finding VelocityThe velocity of motion can be determined by using ticker tape through the following equation:Caution!:t is the time taken from the first dot to the last dot of the distance measured. Example:The diagram above shows a strip of ticker tape that was pulled through a ticker tape timer that vibrated at 50 times a … Read more

A ticker-tape timer consists of an electrical vibrator which vibrates 50 times per second. This enables it to make 50 dots per second on a ticker-tape being pulled through it. The time interval between two adjacent dots on the ticker-tape is called one tick. One tick is equal to 1/50 s or 0.02 s. Example:Find … Read more

Challenging Question 1:A car starts from rest and accelerates at a constant acceleration of 3 ms-2 for 10 seconds. The car then travels at a constant velocity for 5 seconds. The brakes are then applied and the car stops in 5 seconds. What is the total distance travelled by car?   Answer:It’s advisable to list down … Read more

Equation of Uniform Acceleration Most of the motion problems can be solved by the following equations. Therefore, make sure that you memorise all of them. How we know when to use the equation? There are 3 types of motion: motion with uniform velocity motion with uniform acceleration motion with changing acceleration The 4 equations are … Read more

Acceleration Acceleration is defined as the rate of velocity change. It is a measure of how fast the velocity change. Acceleration is a vector quantity. The unit of acceleration is ms-2. An object moving with a velocity that is decreasing is said to be experiencing deceleration. Equation Example:A car travels from a stationary position and … Read more

Speed Speed is defined as the rate of change in distance. It is a measure of how fast the distance change in a movement. Speed is a scalar quantity. The SI unit of speed is m/s (metre per second) Equation of Speed Velocity Velocity is define as the rate of displacement change. It is the … Read more

Play Play Previous Next Distance Definition:  The distance travelled by an object is the total length that is travelled by that object. SI unit: meter (m) Quantity: Scalar Displacement Definition:  Displacement of an object from a point of reference, O is the shortest distance of the object from point O in a specific direction. SI … Read more

https://youtu.be/WNbAvZM-6JQ Kinematics is the research regarding the types of movement of an object without referring to the forces that cause the movement of the object. Movement along a straight line is called linear motion. Under the linear motion, we study the distance and displacement speed and velocity accelerationand the relationship between them.
