Physical Science EOCA Study Guide Practice

Imagine Aria and Arjun are on a treasure hunt. Aria walks in a straight line from the start to the treasure, while Arjun takes a few detours but covers the same ground. What's the difference between the distance Arjun traveled and the displacement Aria covered?

• Distance is a scalar quantity, while displacement is a vector quantity.

• Distance considers only magnitude, while displacement considers both magnitude and direction.

• Distance is always positive, while displacement can be positive, negative, or zero.

• All of the above.

Imagine Emma and Arjun are on a race track. Emma asks Arjun, 'How do you calculate average speed for our race?' How would you explain it to them?

• Divide the total distance traveled by the total time taken.

• Divide the total displacement by the total time taken.

• Multiply the total distance by the total time taken.

• Multiply the total displacement by the total time taken.

Imagine Daniel is racing his bike down a hill. What does the slope of the line indicate on Daniel's motion graph?

• Velocity

• Acceleration

• Displacement

• Speed

Imagine William and Grace are in a science quiz! They're asked: What two factors affect the amount of momentum an object has?

• Mass and Velocity

• Acceleration and Time

• Distance and Force

• Energy and Frequency

Hey there, Maya and Samuel are racing their toy cars and need your help! Can you tell them what the formula for acceleration is?

• a = (Vf - Vi)/t (Change in velocity divided by change in time)

• a = F / m (Force divided by mass)

• a = V / t (Velocity divided by time)

• a = m / F (Mass divided by force)

Imagine Luna and Emma are playing tug of war with equal strength on both sides. What kind of force are they exerting?

• A force that causes an object to accelerate

• A force that causes an object to change direction

• A force that does not cause any change in an object’s motion

• A force that opposes motion

Imagine Henry is playing soccer and he kicks the ball hard. What type of force causes the ball to zoom across the field?

• Frictional force

• Balanced force

• Unbalanced force

• Gravitational force

Evelyn, Aiden, and Benjamin are working on a physics project about forces. They've drawn a force diagram and are puzzled. Can you help them figure out how to calculate the net force from their diagram?

• Add all the forces together

• Subtract all the forces

• Divide the forces by mass

• Multiply the forces by acceleration

Hey there, Sophia and Daniel! Imagine you're in a car that starts slowing down as it approaches a red light. Can you explain what negative acceleration is in this scenario?

Answer explanation

Negative acceleration is when you apply the brakes in a car. You slow down.

Zoe, Hannah, and Olivia are studying physics and they're curious about forces. Can you help them figure out the correct formula for Newton’s Second Law?

• F = m * a

• F = m * g

• F = Δp / Δt

• F = ΔV / Δt
