FORCE AND LAWS OF MOTION

MOTION FIRST EQUATION OF MOTION IS

• V=A-U

• V=U+at

• U=V+at

• A=U+V

Which force produces the change in motion?

• balanced force

• gravitational force

• unbalanced force

• frictional force

3. If these boys are pulling with the same amount of force. What will happen?

• The boy in blue will win.

• The boy in red will win.

• both will not move

• Both will fall down.

Friction and gravity are both examples of a force.

• True

• False

Which one needs a greater net force to move, a kilogram of feathers or a kilogram of iron?

• feathers

• iron

• same

• depends on their friction

The picture of the position vs. time graph shows an object that is...

• accelerating/speeding up

• moving at a constant speed

• not moving

• accelerating/slowing down.

What is Newton's First Law known as? The Law of

• Friction

• Mass

• Inertia

• Gravity

If a force of 26 N is exerted on two balls, one with a mass of 0.52 kg and the other with a mass of 0.78 kg, which ball will have the greater acceleration?

• 0.78 kg

• 0.52 kg

• 0.56

• 0.89

If an action force is a cue ball (white) hitting a billiard ball (various colors) when playing pool, then the reaction force is

• exerted on the table

• not present

• exerted by the billiard ball on the cue ball.

• exerted on all the other billiard balls.

In which direction and with how much force will an object move if you push to the left with 15N of force and your friend pushes to the right with 5N of force?

• up with 10N of force

• left with 10N of force

• down with 5N of force

• right with 10N of force
