How do properties of a ramp affect the force on a car on the ramp?
A. The steeper the ramp is the greater the force of friction is on the car
B. The steeper the ramp is the greater the force of gravity is on the car
C. The longer the ramp is the greater the force of gravity is on the car
B. The steeper the ramp is the greater the force of gravity is on the car

An octopus lives in the same environment as a dolphin. A dolphin uses its tail to move underwater. What structures does the octopus use to move? Think carefully about your answer, then type it in the box below.
Octopus uses its arms to move through the water and those arms can grab onto items to help with movement , some students may note funnel or jet propulsion

Paisley forms the hypothesis that the strength of a push affects the motion of an object. Plan an experimental investigation that could test this hypothesis.
Paisley could test three boxes of the same size and same mass. She could push each one with varying strength and measure the distance it moved.

Eden has designed an experimental investigation on the forces that affect the motion of a balloon rocket. How could she test the effect of gravity on the motion of the balloon?
she could tilt the string at an angle and then compare how the steepness of the string affects the motion of the ballon.
