Nell investigates the motion of a ball. She uses a rubber band wrapped around the legs of a chair to launch the ball. She discovers that the farther she pulls back the rubber band, the faster the ball will travel. Which conclusion should Nell draw?

• Increasing the pull on an object will increase its speed.

• Increasing the weight of an object will increase its speed.

• Increasing the distance an object travels will increase its speed.

• Increasing the energy applied to an object will increase its speed.

Asa measures the speed of a toy car that rolls down four different ramps. He uses a ruler to measure the height of the ramp in centimeters (cm) and a timer to measure time in seconds (s) to collect data. The table shows the measurements and the car speeds. Asa puts a tower of blocks at the bottom of each ramp. Which car and ramp are MOST LIKELY to have enough energy to knock down the tower?

• car and ramp 1

• car and ramp 2

• car and ramp 3

• car and ramp 4

Amos and Lainey have car launchers that use elastic bands to make cars move. The elastic bands can be pulled into four different launch positions and released. Amos and Lainey design and carry out races. The table shows data from their races. Use the data from the races to complete the explanation. Write the letter of ONE correct answer on each line to complete the explanation. Amos lost Races A and D because his car used launch position one. ​ That gives the __________ energy and the ____________ speed.

• least and slowest

• most and faster
