Y9U5T1 - forces

What is a force?

• A measurement of speed
• A measurement of distance
• A push or pull that can change the motion of an object
• A unit of time
• A type of energy

How are forces measured?

• Kilograms (kg)
• Liters (L)
• Meters per second (m/s)
• Newtons (N)
• Watts (W)

What do Newton's Laws of Motion describe?

• The behavior of objects under the influence of forces
• The behavior of objects in space
• The behavior of light waves
• The behavior of atoms
• The behavior of plants

How is speed measured?

• Kilograms (kg)
• Liters (L)
• Meters per second (m/s)
• Newtons (N)
• Watts (W)

How can speed be calculated?

• Dividing distance traveled by the mass of the object
• Dividing distance traveled by the time taken
• Dividing mass by volume
• Dividing time taken by the distance traveled
• Dividing force by acceleration

What does the gradient of a distance-time graph represent?

• Acceleration
• Mass
• Volume
• Speed
• Temperature

What affects the accuracy of distance and time measurements?

• The color of the measuring tool
• The skill of the observer
• The weight of the object being measured
• The time of day
• The smell of the environment

How can units of measurement be converted?

• By counting the number of objects
• By using conversion factors or formulas
• By measuring the temperature
• By using a ruler
• By observing the motion of the object

Why is transportation important?

• It helps in cooking food
• It enables the movement of people, goods, and services from one place to another
• It provides entertainment
• It controls the weather
• It helps in planting crops

What factors should be considered when choosing a mode of transportation?

• The color of the vehicle
• The taste of the food served on the vehicle
• The speed and cost
• The height of the driver
• The shape of the wheels
