Patterns of Forces (TEKS 4.7.A) Quiz

Astronauts plan an investigation to explore the patterns of force on an object. They know that they will experience one of the forces less on the moon. Which force are the astronauts investigating?

• applied

• gravity

• magnetism

Answer explanation

The astronauts are investigating gravity, as it is the force that is weaker on the moon compared to Earth. This reduced gravitational force affects how objects behave in that environment.

Lonny and Aaron are planning an investigation to explore the patterns of forces on a ball. They will roll the same ball on three different surfaces to find out on which surface the ball will roll the farthest. Which tools will TWO they need for their investigation?

• magnet

• notebook

• meterstick

• stopwatch

Answer explanation

Lonny and Aaron need a notebook to record their observations and a meterstick to measure the distance the ball rolls on each surface. A magnet and stopwatch are not necessary for this investigation.

Lin conducted an investigation to explore the effects of forces on a toy cart that rolls down a long ramp. She covered the ramp with different materials and used the same toy cart and ramp for each surface type. The table shows the time she measured for each material. Analyze the data.

Which pattern explains the data Lin gathered?

• The force of friction caused the cart’s time to increase on the foil.

• The force of gravity caused the cart’s time to increase on the carpet.

• The force of friction caused the cart’s time to increase on the carpet.

Answer explanation

The data shows that the cart took longer to roll on the carpet due to increased friction. This friction opposes the motion, causing the cart to slow down, which explains why the time increased on that surface.

Xen is conducting an investigation to explore forces.

Which TWO forces are Xen investigating?

• Friction

• Gravity

• Velocity

• Magnetism

Answer explanation

Xen is investigating forces, and the correct choices are Friction and Gravity. Friction is the force that opposes motion, while Gravity is the force that attracts objects towards each other, both fundamental in understanding forces.

Lukas conducted an investigation to explore patterns in forces in contact on an object. The table shows the distances and times that the ball rolled during his investigation. For each trial, the ball started from rest and a force caused it to move across a smooth surface.

During which trial did the GREATEST amount of force cause the ball to move?

• Trial 1

• Trial 2

• Trial 3

• Trial 4

Answer explanation

Trial 2 had the highest distance covered in the shortest time, indicating the greatest force applied to the ball. According to Newton's second law, greater force results in greater acceleration, leading to more distance traveled.

Which force pulls us towards the earth?

• Gravity

• Magnetism

• Friction

Answer explanation

The force that pulls us towards the Earth is gravity. It is the natural phenomenon by which all things with mass are brought toward one another, specifically towards the center of the Earth.

​ (a)   acts between two touching objects and that opposes motion.

• Friction

• Gravity

• Magnetism

Answer explanation

Friction is the force that acts between two touching objects and opposes their relative motion. It is responsible for slowing down or stopping moving objects, making it the correct answer.
