Forces and Motion Concepts

The video tutorial introduces the concept of forces, describing them as pushes or pulls with magnitude and direction, measured in Newtons. It covers common forces like friction and gravity, and explains how to calculate net force by adding or subtracting forces based on their directions. Practical examples illustrate how net force affects motion, and students are encouraged to practice drawing force vectors.

What is the unit of measurement for force?

• Joules

• Pascals

• Watts

• Newtons

Which force opposes the forward motion of objects?

• Sliding Friction

• Gravity

• Tension

• Magnetic

What type of force is gravity?

• Neutral

• Variable

• Attractive

• Repulsive

What happens when forces acting on an object are balanced?

• The object remains stationary

• The object vibrates

• The object accelerates

• The object changes direction

How do you determine the net force when two forces act in opposite directions?

• Add them

• Multiply them

• Subtract them

• Divide them

In which direction does an object move when acted upon by unbalanced forces?

• In a circular path

• Perpendicular to the forces

• Towards the stronger force

• Towards the weaker force

If a car has a net force of 20 Newtons to the right, what will happen?

• It will stay still

• It will move to the right

• It will move to the left

• It will move upwards

What should be considered when drawing force vectors?

• Color of the line

• Thickness of the line

• Shape of the line

• Length relative to force magnitude

What is the result when forces acting on a car are equal and opposite?

• The car moves upwards

• The car remains stationary

• The car moves in a circle

• The car accelerates

What is the effect of a big push forward on a skateboard?

• It stays still

• It moves backward

• It moves sideways

• It moves forward
