Relationship between force and acceleration

What does mass represent when looking at forces and acceleration?

• The object's weight in kilograms

• The measure of how much matter an object has

• The force applied to an object by gravity

• The amount of space an object occupies

What is acceleration, and how is it defined?

• The measure of how fast an object is moving

• The measure of how far an object has traveled

• The measure of how quickly an object's mass changes

• The measure of how quickly an object's speed is changing

When you start from a standstill and gradually pedal faster on a bike, what are you experiencing?

• Deceleration

• Speed

• Weight

• Acceleration

Which of the following scenarios demonstrates negative acceleration?

• A car slowing down as it approaches a red light

• A car maintaining a constant speed on a straight road

• A car going uphill and gaining speed

• A car moving at a steady pace around a curve

How do we measure acceleration?

• In kilometers per hour (km/h)

• In meters per second (m/s)

• In meters per second squared (m/s²)

• In newtons (N)

Why is acceleration an essential concept in understanding how objects move and interact with forces?

• Acceleration determines the object's weight.

• Acceleration depends on the mass of the object and force applied to it.

• Acceleration explains how objects change direction.

• Acceleration helps us measure the object's volume.
