7th grade review

Please provide the first and last name of the student, for example, Aiden or Lily.

Sophia noticed that when she pushed a book on her desk, it eventually stopped moving. This observation is related to Newton's First Law of Motion, also known as the Law of

• Acceleration

• Friction

• Inertia

• Gravity

Kai is running in a straight line. His velocity is his speed in a given _____________________.

• force

• mass

• direction

• time

In the picture, what force is acting downward on Ava and Rohan while they are skydiving?

• Fluid friction

• gravity

• applied force

• normal force

Mason and Charlotte are skydiving for the first time. Referring to the picture above; what force would they have to take advantage of in order to slow down their descent?

• fluid friction/air resistance

• gravity

• velocity

• inertia

Base your answers to the next three questions on the diagram below and on your knowledge of science. The diagram represents Emma pulling a cart with a box on it. The arrow represents the direction in which Emma is moving. Check all the forces acting on the cart force acting on the cart.

• friction between the wheels and the road

• normal force of the road pushing up on the cart

• applied force from Emma pulling the cart

• gravity pulling down on the cart

• all of the above

Noah is pushing a shopping cart at the grocery store. Identify the force between the wheels of the cart and the ground surface that opposes forward motion of the cart.

• friction

• acceleration

• velocity

• normal force

Explain why a book may continue to slide forward if a car suddenly stops moving.

• speed

• velocity

• inertia

• acceleration

Abigail and Henry are observing the gravitational force between two objects. The gravitational force between the objects is most affected by their

• motion and volume

• motion and distance apart

• mass and volume

• mass and distance apart

Grace and Priya are discussing what keeps planets in orbit around the Sun. What is the primary force responsible for this?

• the reflection of sound energy

• the flow of electricity in a closed circuit

• keeping planets in orbit around the Sun

• refracting light energy
