Acceleration and Momentum

Acceleration and Momentum

By Gilson Granil

Recall of Speed and Velocity

​

SPEED is how fast an object's position changes over time.

​

To calculate speed:

​Speed = distance ÷ time

​

Alef 112-113 Acceleration and Momentum

Recall of Speed and Velocity

​

VELOCITY is the measurement that combines both the speed and the direction of a moving object.

​

To calculate velocity:

Velocity = speed + direction

​

Alef 112-113 Acceleration and Momentum

Multiple Choice

Which of the following is speed?

• 3 km/hr

• 3 km/hr East

• both are correct

Multiple Choice

Which of the following is velocity?

• 3 km/hr

• 3 km/hr East

• both are correct

What is Acceleration

​

​

​

​

​

​

​

Acceleration is the change in velocity over time for an object.​

​

​

Multiple Choice

Acceleration is defined as the CHANGE in 

• time it takes for one place to move to another place. 
• velocity of an object.
• velocity divided by the time interval 

To calculate acceleration, this equation will be used.​

Units of Acceleration:

1. cm/s²

2. m/s²​

Multiple Choice

Calculate the acceleration of a box when it moved to the left side at 4 m/s in 2 seconds.

• 8 m/s²

• 2 m/s²

• 2 m/s

1. Speeding Up

​3 Ways an Object can Accelerate

​

2. Slowing Down​

3. Changing Direction​

Multiple Choice

Which is an example of acceleration?

• a book falling from the table

• a runner who stopped at the finish line

• a car moving at constant speed
