Joseph throw a ball by hand as the ball acted upon by unbalanced force, how the ball will move?

• slow down, change direction, and then speed up until it falls to the ground.

• travel at the same speed until it hits the ground.

• speed up keep its same direction, and then slow down as it touch to the ground.

The amount of force you need to move an object depends on?

• Direction

• velocity

• mass

• speed

A truck was covering 8 meters in 2 seconds. What is the average speed of the truck?

• 6m/s

• 5m/s

• 4m/s

• 10m/s

There are four friends wants to race.

1st friend -Covers 30 yards in 4 seconds

2nd Friend - Covers 30 yards in 5 seconds

3rd friend - Covers 30 yards in 6 seconds

4th friend - Covers 30 yards in 10 seconds

Which of the friend has speed of 5 yards per second?

• Friend 1

• Friend 2

• Friend 3

• Friend 4

If you want to move a large and heavy box on a truck, we know it will be easier to move the heavy and large objects by using inclined plane because the inclined plane will —

• Inclined plane reduces the force.

• increase the work done on the crate.

• Inclined plane increases the Force.

• Increase the work .

If you are driving car and covering 5 meters in 2.5 seconds. What is the your average speed?

• 3m/s

• 4m/s

• 2m/s

• 1m/s

There are two ramps

1- ramp with longer distance

2- ramp with smaller distance

which ramp you will use in order to use less force to move a object.

• Ramp with smaller distance

• Ramp with longer distance
