Sixth Grade Assignment: Force Activity

ASSIGNMENT: PROBLEMS WITH FORCE

In the problems below, find the Force.

Use F = m x a

Look at the practice problems below to guide your work.

Examples:

A.    If a car weighs 1000 Kg and has an acceleration of 10 m/s², what is the force of that car?

F = m x a

F = (1000 Kg)x(10m/s²)

F = 10,000 Kg x m/s²

F = 10,000 Newtons (N)

Answer: The force on that car will be 10,000 Newtons.

B.     If a bowling ball weighs 12 Kg and somebody throws it with an acceleration of 2 meters per second squared, what is the force of the bowling ball?

F = m x a

F = (12 Kg)x(2 m/s²)

F = 24 Kg x m/s²

F = 24 Newtons (N)

Exercises

1. If a basketball player shoots a basketball that weighs 1 kg, with an acceleration of 3 meters per second squared, what would be its Force?

2. An Olympic athlete throws a hammer with an acceleration of 12 meters per second squared. If the hammer weighs 2 kg, with what force does the athlete throw the hammer?

3. A tennis player hits a tennis ball that weighs 0.2 Kg with an acceleration of 16 meters per second squared, with what force did the tennis player hit the tennis ball?

4. If a ping-pong player hits a ping-pong ball with an acceleration of 14 meters per second squared, and the ball weighs .005 Kg, with what force did the player hit the ball?

Extra Credit Problem: If a space rocket weighs 2,500Kg and at the moment of launch, the acceleration of the rocket is of 50 meters per second squared, what is the Force on the rocket?
