Explain how unequal forces acting on an object can cause it to move.

• Unequal forces balance each other out, causing no movement.

• Unequal forces cause the object to move in the direction of the stronger force.

• Unequal forces cause the object to move in the opposite direction of the stronger force.

• Unequal forces have no effect on the object's motion.

Design a simple experiment to test how the angle of a ramp affects the speed of a toy car.

• Use a flat surface and measure the time it takes for the car to travel a set distance.

• Use ramps of different angles and measure the time it takes for the car to travel a set distance.

• Use a stopwatch to measure how long the car takes to stop.

• Use a scale to measure the weight of the car.
